Question

A circular pizza is divided into eight equal slices. The outer edge of the crust from one piece measures 8 inches. What is the diameter of the pizza to the nearest inch?

Answer 1

Explanation:

If the pizza is cut into 8 pieces and each piece has an outer crust of 8 inches, then the circumference of the pizza is 64 inches. We can use that to find the diameter in the circumference formula:

C = πd and

64 = π d so

64/π = d so

d = 20.37 inches so 20 inches to the nearest inch
