Manny loves to eat Cajun pizza. Each square inch of pizza is 8 calories. He orders a slice of pizza from a pizza with a diameter of 16 inches that is cut with a central angle of 20 degrees. How many calories does he eat?

• math -

The area of the pizza slice is

A = (1/18)*(1/4)*pi*d^2 in^2
because 20 degrees is 1/18 of a full circle.

Multiply that area by the Calories per square inch andsee what you get. One number on your list will be very close.

calories= 20/360 * PI 8^2 * 8
