Question

A pizza has a diameter of 12 inches. What is the approximate circumference of the pizza?

Answer 1

c = 2 x pi x radius

2 x pi x 6

c = 12 pi or 37.69 inches

Answer 2

The approximate circumference of the pizza is
`37.7\ in`

Explanation:

we know that

The circumference of a circle is equal to

`C=\pi D`

where

D is the diameter

In this problem we have

`D=12\ in`

substitute

`C=\pi (12)=37.7\ in`
