Answer 2

Answer:

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

Step-by-step 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

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