if the daimeter of a solid cylinder with lenght 140cm is 8cm , find its curved surface area ,
Answer : The curved surface area of solid cylinder is [tex]3520cm^2[/tex]
Step-by-step explanation :
As we are given that:
Diameter of solid cylinder = 8 cm
Length or Height o solid cylinder = 140 cm
Formula used to calculate the curved surface area of cylinder is:
Curved surface area of cylinder = [tex]2\pi r\times h[/tex]
where,
r = radius of cylinder
h = height or length of cylinder
Radius of cylinder = [tex]\frac{Diameter}{2}=\frac{8cm}{2}=4cm[/tex]
Now putting all the given values in above formula, we get:
Curved surface area of cylinder = [tex]2\times \frac{22}{7}\times 4cm\times 140cm[/tex]
Curved surface area of cylinder = [tex]3520cm^2[/tex]
Therefore, the curved surface area of solid cylinder is [tex]3520cm^2[/tex]
Given:
Diameter of a solid cylinder = 8cm
Length (height) of cylinder = 140 cm
To find:
The curved surface area of the cylinder.
Solution:
We have,
Diameter = 8cm
Radius = [tex]\dfrac{8}{2}=4\text{ cm}[/tex]
Height = 140 cm
Curved surface area of a cylinder is
[tex]CSA=2\pi rh[/tex]
where, r is radius and h is height.
Putting r=4 and h=140 in the above formula, we get
[tex]CSA=2\times \dfrac{22}{7}\times 4\times 140[/tex]
[tex]CSA=2\times 22\times 4\times 20[/tex]
[tex]CSA=3520[/tex]
Therefore, the curved surface area of the cylinder is 3520 square cm.

Find the formula for the area A and the perimeter P of the shape shown find the area and perimeter when R is 5 cm find R when A is 100cm2 find r when P is 50cm find the value of r that makes A = p numerically
Answer:
1)Area; A = ¼πr²
Perimeter; P = πr/2 + 2r
2)A = 19.63 cm²
P = 17.85 cm
3) r = 8.885 cm
4) r = 14 cm
Step-by-step explanation:
This is a quadrant of a circle. Thus;
Area of a circle is πr². A quadrant is a quarter of a circle. Thus;
Formula for Quadrant Area is; A = ¼πr²
A) Perimeter of a circle is 2πr. Thus, perimeter of a quadrant is a quarter of the full circle perimeter.
Formula for the quadrant perimeter in the image given is;
P = 2πr/4 + 2r
P = πr/2 + 2r
B) When r is 5 cm;
A = ¼π(5)²
A = 19.63 cm²
P = π(5)/2 + 2(5)
P = 17.85 cm
C) when A is 100cm²:
¼πr² = 100
r² = 100 × 4/π
r² = 78.9358
r = √78.9358
r = 8.885 cm
D) when P = 50 cm.
50 = πr/2 + 2r
50 = (½π + 2)r
r = 50/(½π + 2)
r = 14 cm

Answer:
m<1 = 54
m<3 = 54
m<4 = 126
Step-by-step explanation:
<1: <2 and <1 are supplementary angles.
<3: <2 and <3 are supplementary angles. <1 and <3 are vertical angles.
<4: <2 and <4 are vertical angles.
Supplementary angles equal to 180 degrees.
Vertical angles are equivalent.
Let's solve for <1.
<2 + <1 = 180 --> Due to supplementary angles
126 + <1 = 180 --> Substitution
126 + <1 - 126 = 180 - 126 --> Subtracted 126 on both sides
<1 = 54 --> Simplified
Let's solve for <3.
<3 = <1 --> Due to vertical angles
<3 = 54 --> Substitution
Let's solve for <4.
<4 = <2 --> Due to vertical angles
<4 = 126 --> Substitution
Therefore, m<1 = 54, m<3 = 54, and m<4 = 126
Hope this helped! <3

1 is 54 degrees

Answer:
The area of the lateral surface of the cube is 12.96 cm²
Step-by-step explanation:
The lateral surface area
4 × (1.8 cm)²
An objects lateral surface are the surfaces of the object that exclude the top and bottom surfaces
In a cube, the lateral surface are the vertically oriented (with respect to the base and the top which are then oriented horizontally) surfaces of the cube
Therefore, the lateral surface area of the cube consist of four vertically oriented equal sized faces, each with side 1.8 cm
The area of the lateral surface of the cube = The area of the four vertically oriented faces of the cube
∴ The area of the lateral surface of the cube = 4 × 1.8 cm × 1.8 cm = 12.96 cm.²

3. The sales director a manufacturer decides to try out two different methods of distributing and seling a new video game. The game is sold to a retailer for a net profit of $9.90 on each game . The game is also sold at the factory outlet for a net profit of $10.99 on each game. If 500 games are sold by the outlet, many more would have to be sold by the retailer in order for the profit to be about equal
Answer:
The number of games that need to be sold to the retailer in order for the profit to be about equal is approximately 555 games
Step-by-step explanation:
The given parameters are;
The net profit at which each game is sold to a retailer = $9.90
The net profit at which each game is sold at the factory outlet = $10.99
The number of units sold by the outlet = 500
The amount in profit from selling at the factory outlet = 500 × $10.99 = $5,495.00
The number of games that need to be sold to the retailer in order for the profit to be about equal is given as follows;
Let "x" represent the number of games that need to be sold to the retailer in order for the profit to be about equal
Therefore, we have;
x × $9.90/game = $5,495.00
x = $5,495.00/($9.90/game) = 555.[tex]\overline {05}[/tex] games ≈ 555 games
Therefore, the number of games that need to be sold to the retailer in order for the profit to be about equal = x ≈ 555 games.

The Hendersons have a sedan and a minivan. the difference in mileage of the two vehicles is greater than 4,500 miles. The minivan has 12,755.25 miles. determine the possible number of miles on the sedan. then interpret the solution.
Answer:
Number of miles is either less than 8255.25 or greater than 17255.25.
Step-by-step explanation:
Given that :
Difference in mileage of the sedan and minivan is > 4500
Mikeage of minivan = 12755.25
Possible number of miles on the sedan :
Mileage on minvan ± difference in mileage ;
12755.25 ± 4500
12755.25 + 4500 = 17255.25
12755.25 - 4500 = 8255.25
This means that the possible number of miles on the sedan is either greater than 17255.25 OR less Than 8255.25
-4x+3y=6 in
slope intercept
Answer:
y=4/3x+2
Step-by-step explanation:
The equation is in standard form right now, which is ax+by=c
your question is asking for slope intercept form, which is y=mx+b
so we need to isolate y onto 1 side
-4x+3y=6
add 4x to both sides
3y=4x+6
divide by 3 on both sides
y=4/3x+2

What is the area of the given circle? Use 3.14 for it.
A)
56.52 cm2
B)
254.34 cm2
C)
324.09 cm2
D)
1017.36 cm2
Answer: B. 254.34 cm^2
Step-by-step explanation:
The area of a circle is pi times the radius squared.
Using the diameter we have to find the radius.
The diameter is two times the radius meaning that the radius is half the diameter.
18/ 2 = 9
The radius will be 9 cm
Now using the formula v= pi * r^2 , input the value for pie and the radius and solve for v the volume
v = 3.14 * 9^2
v= 3.14 * 81
v = 254.34 cm^2
Answer:
The answer would be B) 254.34 cm2

He highest priced diamond ever sold at auction weighed 69.42 carats and sold for $1,050,000. A carat is equal to 0.2 grams. What was the weight of this diamond in grams?
Answer:
13.884 grams
Step-by-step explanation:
From the question:
1 carat = 0.2 grams
The highest priced diamond = 69.42 carats.
Hence:
1 carat = 0.2 grams
69.42 carats = x grams
x grams = 69.42 × 0.2 grams
x grams = 13.884 grams
Hence, the weight of the highest priced diamonds is 13.884 grams.

5(x - 1) and 5x - 1
is it equivalent
Answer:
no
Step-by-step explanation:
5(x - 1) = 5x - 5
5x - 1 = 5x - 1
No, it is not equivalent
The required, 5(x - 1) and 5x - 1 are not equivalent expressions.
Let's expand 5(x - 1):
5(x - 1) = 5 * x + 5 * (-1) = 5x - 5
On the other hand, 5x - 1 is already in its simplified form.
As you can see, the expressions 5(x - 1) and 5x - 1 have different forms. The first expression involves distributing the 5 to both terms inside the parentheses, while the second expression is already simplified and cannot be further combined.
For example, if we substitute x = 2 into both expressions, we get:
5(2 - 1) = 5 * 1 = 5
5 * 2 - 1 = 10 - 1 = 9
Since 5 and 9 are not equal, it confirms that the two expressions are not equivalent.

A combination lock is to have 4 digits (using the numbers from 1 to 9 (ie No Zero)How many different combinations are there that have all different numbers.
Answer:
3024
Step-by-step explanation:
You have to think of this in choices. You have 9 choices for the first lock (because there are 9 numbers). We would have 9 choices for the second lock, but we used one number for the previous one. So we would have 8 choices. We would continue with 7 choices for the third lock and 6 for the fourth.
