To find the area of a circle, you can use the formula:
\[
\text{Area} = \pi r^2
\]
where \( r \) is the radius of the circle.
Given that the radius \( r \) is 12 feet and using \( \pi \approx 3.14 \):
\[
\text{Area} = 3.14 \times (12)^2
\]
Calculating \( (12)^2 \):
\[
(12)^2 = 144
\]
Now substituting back into the area formula:
\[
\text{Area} = 3.14 \times 144
\]
Calculating that product:
\[
3.14 \times 144 = 452.16
\]
So, the estimated area of the circle to the hundredths place is:
\[
\text{Area} \approx 452.16 \text{ square feet}
\]
The correct response is:
**452.16 square feet**
\[
\text{Area} = \pi r^2
