Question

The circumference of a pizza is approximately 56.52 inches. One-fourth of the pizza has been eaten. Enter the area of the remaining pizza, in square inches. Round your answer to the nearest hundredth. Use 3.14 for π.

Answer 1

C=πd, d=56.52/π

A=(πd^2)/4

and there is only 3/4 of the pizza remaining so:

A=(3/4)(56.52^2)/(4π) and we are told to approximate π≈3.14

A=(3/4)(56.52^2)/(4*3.14)

A≈190.755

A≈190.76 in^2 (to nearest one-hundredth of a square inch)
