To find the area of a circle, you can use the formula:
\[
\text{Area} = \pi r^2
\]
Given that the radius \( r = 12 \) feet and using \( \pi \approx 3.14 \), we can substitute the values into the formula:
\[
\text{Area} = 3.14 \times (12)^2
\]
Calculating \( (12)^2 \):
\[
(12)^2 = 144
\]
Now substitute this back into the formula:
\[
\text{Area} = 3.14 \times 144
\]
Now perform the multiplication:
\[
\text{Area} = 452.16
\]
Rounding to the nearest hundredth, the area of the circle is:
\[
\text{Area} \approx 452.16 \text{ square feet}
\]
\[
\text{Area} = \pi r^2
