Question

The area of an extra large circular pizza from Gambino's Pizzeria is 484 pi cm squared . What is the diameter of an extra large pizza from Gambino's Pizzeria?

Answer 1

44cm

Explanation:

Answer 2

The diameter is equal to
`44\ cm`

Explanation:

we know that

The area of a circle (pizza) is equal to

`A=\pi r^(2)`

In this problem we have

`A=484\pi \ cm^(2)`

substitute and solve for r

`484\pi=\pi r^(2)`

simplify

`484=r^(2)`

square root both sides

`r=22\ cm`

Find the diameter

`D=2r=2(22)=44\ cm`
