To calculate the area of a circle, you can use the formula:
\[ \text{Area} = \pi r^2 \]
Where \( r \) is the radius of the circle. In this case, 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 formula:
\[ \text{Area} = 3.14 \times 144 \]
Calculating \( 3.14 \times 144 \):
\[ 3.14 \times 144 = 452.16 \]
Therefore, the area of the circle is:
\[ \text{Area} \approx 452.16 \text{ square feet} \]
The correct response is: 452.16 square feet.
