The diagram shows a square pizza box with side lengths of 16 inches. In the box is a circular pizza with a radius of 8 inches. What is the difference between the area of box and the pizza?

Question

Help please i can't figure it out i spent hour trying to get it.

Answer 1

the box area = 16 x 16 = 256 in^2

the pizza area = pi(r^2) = pi(8^2) = 64pi = about 64(3.14159) = about 201.06

difference = 256-64pi = about 54.94 square inches
