Answer:

Step-by-step explanation:

the formula for calculating the perimeter of a circle (the circumference C) is:

2π * r

And the area is:

π * r²

r is the radius.

Radius is the half of the diameter. The diameter here is equal to two square. One square is 5 of side.

The diameter is 10 and the radius is 5

<h3>C = 2 * 3.14 * <u>5</u> = 31.4</h3><h3>A = 3.14 * <u>5²</u> = 3.14 * 25 = 78.5</h3>

It is the same for the other circle

Rock singer and writer Beep Blair is paid 11.5% on her CD sales and music downloads. Last year, she sold 1.22 million CDs and 2.
Dmitrij [34]

Using proportions, it is found that she earned $943,000 from CD sales.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

The total amount involved in the sells and downloads are:

1.22 x 5 + 2.1 x 1 = 8.2 million.

She was paid 11.5% of that, hence:

0.115 x 8.2 = 0.943 million = $943,000.

She earned $943,000 from CD sales.

What is the value of x?
ryzh [129]

Answer:

Step-by-step explanation:

The top triangle is similar to the whole triangle because of AAA

Then we know that the corresponding sides are similar

9/81=(3x-20)/(3x-20+56)

1/9=(3x-20)/(3x+36)

cross multiply

9(3x-20)=3x+36

27x-180=3x+36

24x=216

x=9
