The box is a square. It's perimeter is 48 inches. The pizza has a circumference of 37.68 inches. What is the difference in the area of the pizza and the area of the pizza box? Round to the nearest tenth

Respuesta :

area of box:

48/4 = 12

12^2 = 144 square inches


area of pizza:

area = C^2/4π

37.68^2 = 1419.7824/12.56 = 113.04 square inches


difference : 144 - 113.04 = 30.96 inches, rounded to nearest tenth = 31.0 inches
