Answer:

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

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