Answer 1

44

Explanation:

Answer 2

The diameter of an extra large pizza from Gambino's Pizzeria is
`44\ cm`

Explanation:

we know that

The area of a circle (circular pizza ) is equal to

`A=\pi r^(2)`

we have

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

substitute in the formula and solve for the radius r

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

Simplify

`484=r^(2)`

`r=22\ cm`

Find the diameter

Remember that the diameter is two times the radius

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