Answer:

The area of circle 1 is 9 times greater than area of circle 2.

Step-by-step explanation:

Given that:

Radius of circle 1 = 12

Area of circle 1 = πr²

Area of circle 1 = [tex]3.14*(12)^2 = 3.14*144[/tex]

Area of circle 1 = 452.16

Radius of circle 2 = 4

Area of circle 2 = [tex]3.14*(4)^2 = 3.14*16[/tex]

Area of circle 2 = 50.24

Let,

x be the number of times circle 1 is bigger than circle 2.

Area circle 1 = x * Area circle 2

[tex]\frac{452.16}{50.24}=\frac{50.24x}{50.24}\\\\x=9[/tex]

Hence,

The area of circle 1 is 9 times greater than area of circle 2.

Answer:

69.08

Step-by-step explanation:

The equation for circumference is C = 2πr and the equation for area is A = πr^2. First, do 379.94 = 3.14r^2. This means that r^2=121 so r=11. Now plug it in to C=2πr so it becomes C=2π(11). So C=22π or 69.08.

Question:

Find the circumference of the circle. Use 3.14 for π.

5 in.

Answer:

15.7 inches

Step-by-step explanation:

Identify the diameter of the circle.

d = 5 in.

Use the formula.

C = πd

C = π(5) Substitute 5 for d.

C ≈ 3.14(5) Substitute 3.14 for π.

C ≈ 15.7 Multiply.

The circumference of the circle is about 15.7 inches.

Answer:

Equation of line passing through (3,2) and parallel to line [tex]y = \frac{1}{3}x-3[/tex] is:

[tex]y = \frac{1}{3}x+1[/tex]

Step-by-step explanation:

Given equation of line is:

[tex]y = \frac{1}{3}x-3[/tex]

Slope-intercept form of a line is given by:

[tex]y = mx+b[/tex]

Comparing the given equation of line with general form we get

m = 1/3

Let m1 be the slope of line parallel to given line

Then the equation of line will be:

[tex]y = m_1x+b[/tex]

We know, "Slopes of two parallel lines are equal"

Which means

[tex]m_1 = m\\m_1 = \frac{1}{3}[/tex]

Putting the value of slope

[tex]y = \frac{1}{3}x+b[/tex]

Putting the point (3,2) in the equation

[tex]2 = \frac{1}{3}(3)+b\\2 = 1+b\\b = 2-1\\b = 1[/tex]

Final equation of line is:

[tex]y = \frac{1}{3}x+1[/tex]

Hence,

Equation of line passing through (3,2) and parallel to line [tex]y = \frac{1}{3}x-3[/tex] is:

[tex]y = \frac{1}{3}x+1[/tex]

The measures 3.1, 4.8, and 10.2 cannot be the side lengths of a triangle.

"It states that the sum of any two sides must be greater than the third side."

For given question,

we have been given the measures 3.1, 4.8, and 10.2  

We need to check whether given measures can be the side lengths of a triangle.

First we check whether the given measures obey triangle inequality or not.

3.1 + 4.8 = 7.9

7.9 < 10.2

This means, the measures 3.1, 4.8, and 10.2 do not obey triangle inequality

Therefore,  the measures 3.1, 4.8, and 10.2 cannot be the side lengths of a triangle.

Answer:

32%

Step-by-step explanation:

Area of rectangle ABCD = 20 * 30 = 600 Sq cm

After increasing the length and width of the rectangle by 20% and 10% respectively.

New length = 30 + 20% of 30 = 30 + 6 = 36 cm

New width = 20 + 10% of 20 = 20 + 2 = 22 cm

Area of new rectangle = 36*22 = 792 Sq cm

Increase in area = 792 - 600 = 192 Sq cm

Percentage increase in area

= (192/600) *100

= 32%

Answer:

(-20)

Step-by-step explanation:

-4 - 2(4 + (-2) )³ = -4 - 2(4 - 2)³

                        = -4 - 2*(2)³

                       = -4 - 2* 8

                      = -4 - 16

                     = -20

Answer:

4x + y = -12

Step-by-step explanation:

Standard form is Ax + By = C

First, distribute the -4:

у + 4 = -4(х + 2)

y + 4 = -4x - 8

Subtract 4 from both sides:

y = -4x - 12

Add 4x to both sides:

4x + y = -12

So, the standard form equation is 4x + y = -12

Answer:

9°

Explanation:

So, since the arrow is pointing to a RIGHT angle, you have to know the right angle's degree is 90° so set up an equation.

11x - 9 = 90

Now you solve it. Here's a step by step:

11x - 9 = 90

Add nine to nine and ninety. Since the nine in this equation is negative, it'll cancel it out. Now here's what you have left to solve:

11x = 99

Divide -11 from 11 and 99.

x = 9

If you feel like you're wrong, fill it in!

11(9) - 9 = 90

11 x 9 = 99

99 - 9 = 90

There you go!
