#### Explanation:

The area of a circle is given by formula:
color(blue)(pir^2
Where,
$\pi$ has a constant value of $\approx 3.14$
and $r$ denotes the radius.

The radius of the circle is $r = 6$ft

The area $= \pi {r}^{2} \approx 3.14 \times {\left(6\right)}^{2}$

$\approx 3.14 \times \left(36\right)$

$\approx 113.04$ square feet
