Area of pizza is pi*r^2=25 pi in^2

The correct answer is 9.8 in^2.

Answer by greenestamps(13200)   (Show Source): You can put this solution on YOUR website!

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.
