What is the area of each circle Use 227 for pi 1 r 6 ft 2 d

What is the area of each circle.

Use 22/7 for pi.

1. r = 6 ft

2. d = 22 in.

Thanks inadvance!.

1. First write down the formula for area of a circle:

A = pi * r ^2

Then substitute what you know:

A = (22/7) x 6 x 6 and multiply

Remember to always put area in square measure. So..

A = 113.14 square feet

2. Write down the formula:

A = pi * r^2

3. Substitute what you know:

A = (22/7) x 11 x 11

(Remember that d/2 = r)

4. Multiply and put the answer in square inches:

380.29 square inches
