A circular pizza that is 18 inches in diameter is cut into 8 equal slices. What is the area of a single slice?

31.8 in^2

Step-by-step explanation:

The area of a circle is pi*radius^2.

r=.5d=18/2=9

A = (3.14159) (9^2) = (3.14159) (81) = 254.5

And if each peice is of equal area, the area of one peice will equal:

254.5/8=31.8
