Find the surface area of the cylinder. Round your answer to the nearest tenth. Please help.

Answers

The solution is: the surface area of the cylinder is 34.16 cm².

Here, we have,

from the given diagram, we get,

For surface area of a cylinder:

A = 2(π) × (radius) × (height) + 2(π)×(radius squared)

For the first half of that equation:

2(π) × (radius) × (height)

2(3.14)×(0.8)×(6)

= 30.14 cm²

Now the second half of that equation, the area of the circle ends:

2(π)×(radius squared)

= 2×(3.14)×(0.8)×(0.8)

= 4.02 cm²

Add them up:

30.14 cm²+4.02 cm² = 34.16 cm²

Hence, The solution is: the surface area of the cylinder is 34.16 cm².

Consider the equation

8x - 2y = 24

Determine if each statement is True or False.

A. The x-intercept is 3.

B. The y-intercept is 12.

C. It is equivalent to y=4x-12.

Answers

a) true

b) false

c) true

Step-by-step explanation:

let's determine the first statementto determine x-intercept substitute y=0

so,

8x-2y=24

8x-2.0=24

8x=24

x=3

therefore

the first statement is true

let's determine the second statement

to determine y-intercept substitute x=0

so,

8x-2y=24

8.0-2y=24

-2y=24

y=-12

therefore

the second statement is False

to determine the third statements

we need to turn the given equation into this formy=mx+blet's solve:

8x-2y=24

-2y=-8x+24

y=4x-12

therefore,

the third statement is also true

There are 20 students in a class, 12 of the students are girls
Find the ratio of number of girls to the number of boys
express your ratio in the form n: 1

Answers

Answer:

1.5 : 1

Step-by-step explanation:

Given the number of girls = 12 , then

number of boys = 20 - 12 = 8

Ratio of girls : boys = 12 : 8 = 3 : 2 = 1.5 : 1

The ratio of the number of girls to the number of boys  express your ratio in form 1.5: 1.

Given that,

There are 20 students in a class, 12 of the students are girls,

We have to determine,

Find the ratio of the number of girls to the number of boys  express your ratio in the form n: 1.

According to the question,

Number of students in the class = 20

Number of girls in the class = 12

Then,

Number of boys in the class = 20 - 12 = 8

The ratio of the number of girls to the number of boys  express your ratio in the form n: 1.

The ratio of girls and boys is,

[tex]= \dfrac{number \ of \ girls}{number \ of \ boys}\\\\= \dfrac{12}{8}\\\\= \dfrac{6}{4}\\\\= \dfrac{3}{2}\\\\= \dfrac{1.5}{1}\\\\= 1.5;1[/tex]

Hence, The ratio of the number of girls to the number of boys  express your ratio in form 1.5: 1.
