The area \( A \) of a circle is calculated using the formula:
\[ A = \pi r^2 \]
Where \( r \) is the radius of the circle. Given that the radius is 12 feet and using \( \pi \approx 3.14 \):
\[ A = 3.14 \times (12)^2 \] \[ A = 3.14 \times 144 \] \[ A = 452.16 \text{ square feet} \]
Therefore, the area of the circle is 452.16 square feet.
The correct response is: 452.16 square feet.
