You and your friend ordered a 12 cut pizza with a radius of 8 inches. How much cheese is needed to cover one slice of the pizza? Hint: Find the area of one slice. Round your answer to the nearest tenth

A = pi * r^2
A = 3.14 * 16
A = 50.24 square inches
50.24 / 12 = _______ square inches 
4.2

Right.

What if you teacher reqiures to use the actual pie on the calculator instead of typing it in
