If a circle has a circumference of 32 highlight%28cross%28pie%29%29 pi inches, what is the area in terms of highlight%28cross%28pie%29%29 pi?
~~~~~~~~~~~~~~~~ 

If a circle has a circumference of 32%2Api,  then its radius is  %2832%2Api%29%2F%282%2Api%29 = 16 inches.


Hence, its area is  pi%2Ar%5E2 = pi%2A16%5E2 = 256%2Api square inches.     ANSWER

C=2pi*r
32pi=2pi*r
r=16 in
A=pi*r^2
=pi*256 in^2

Circumference of a circle = 2%2Api%2Ar
Given circumference = 32pi
32pi+=+2%2Api%2Ar
r=+16
Area of a circle = pi%2Ar%5E2=pi%2A%2816%29%5E2=256pi
