Area of pizza is pi*r^2=25 pi in^2
Divide that by 8
3.125 pi in^2 or 9.82 cm^2
9.8 cm^2 answer

The radius is 5; the area is pi times radius squared.

Since the problem is multiple choice and the answers are not close together, estimate using 3 for pi.

Now divide that area by 8 to find the area of one piece.

Only one of the answer choices is close to that.
