Answer:
The diameter of an extra large pizza from Gambino's Pizzeria is [tex]44\ cm[/tex]
Step-by-step explanation:
we know that
The area of a circle (circular pizza ) is equal to
[tex]A=\pi r^{2}[/tex]
we have
[tex]A=484\pi\ cm^{2}[/tex]
substitute in the formula and solve for the radius r
[tex]484\pi=\pi r^{2}[/tex]
Simplify
[tex]484=r^{2}[/tex]
[tex]r=22\ cm[/tex]
Find the diameter
Remember that the diameter is two times the radius
[tex]D=2(22)=44\ cm[/tex]
