Question

The circumference of a circle is 20 pi. What is the area of the circle in terms of pi?

Answer 1

The answer is 40π in.

Explanation:

The way you can find circumference using radius is this formula below:

c= 2π*r

c=6.8*20

c=40π in.

I hope this helped. Good luck on the rest of your exam! :)

Answer 2

area=100π

Explanation:

circumference=2πr

20π=2πr

20=2r

r=10

area=πr^2

area=π10^2

area=100π
