Answer:

9852 Rounded to the nearest whole number.

Explanation:

C = 2
$\pi$ r Fill in what we know to solve for r

176 = 2
$\pi$ r Divide both side by 2
$\pi$

r = 28 rounded to the nearest whole number.

The formula for the area of a circle is

A = 4
$\pi$
r^(2)

A = 4
$\pi$
28^(2)

A = 9852 Rounded to the nearest whole number
