Question

A 12 inch diameter pizza is cut into eight equal pieces what is the area of each piece

Answer 1

4.5π in^2

Explanation:

First, find the area of the entire pizza. Since the pizza diameter is 12 inches, the radius is 6 inches. The area is A = π(6 in)^2 = 36π in^2.

Next, divide this total area by 8, since we want 8 equally sized pieces.

36π in^2

-------------- = 4.5π in^2 (answer)

8

Answer 2

A = 1/8·pi·r^2 = 1/8·pi·6^2 = 9/2·pi = 14.14 inches²
