Question

A bakery sells apple pies for $11.05. If the pie has a diameter of 8 inches, what is the approximate cost per square inch of the apple pie? Round to the nearest hundredth.

A. $0.88
B. $0.05
C. $0.44
D. $0.22

Answer 1

D. $0.22

Explanation:

The pie is shaped like a circle

The area of a circle with radius r = πr²

This circular pie has a diameter of 8 inches

Radius = diameter/2 = 8/2 = 4 inches

Surface area of pie = π 4² = 16 π square inches

Cost of pizza = $11.05

Cost per square inch = Cost/Area = 11.05/16π = $0.22 rounded to nearest cent
