Step-by-step explanation:

With round pizza we need to

find the area of each pizza in

square inches, then determine

the difference.

The area of a circle is given by:

A = πr2

12 inch diameter, radius = 6

a = π(62) = 36π in2

8 inch diameter, radius = 4

a = π(42) = 16π in2

Difference: 36π - 16π = 20π in2

using 3.14 for pi, the difference is

20(3.14) = 62.8 in2
