Answer:

$9\pi ft^2$

Explanation:

$\text {Formula for the area of a circle:}\\ A=\pi r^2$

The diameter is given. The radius of a circle is half it's diameter.

$6/2 = 3\\\text {Radius: } 3$

Apply the Formula (using 3.14 for pi):

$A=\pi(3)^2\\A=\pi(9)\\A = 9\pi$

The answers are in exact form.

The circle's area should be
$9\pi ft^2$ .

I do not see C or D's options, but choose the answer that is the closest to
$9\pi$ .
