How do you figure the area of a 12 inch pizza?

Answer 1

This is the same as finding the area of any circle.

It's the radius squared times pi, where pi is approximately 3.1415927

The formula is: area = pi * r Squared

The radius is half the diameter. So the radius of your 12 inch Pizza is 6 inches.

Squared means multiplying it by itself. So 6 squared is 36.

Multiply 36 by pi and you get 113.0973372 square inches, the area of a 12 inch pizza.

This is the answer to 7 decimal places, probably more precise than you need to know.

Answer 2

By using the area formula of a circle which is: pi*radius squared
