The area \( A \) of a circle is calculated using the formula:
\[
A = \pi r^2
\]
where \( r \) is the radius.
Given a radius \( r = 12 \) feet and using \( \pi \approx 3.14 \):
\[
A = 3.14 \times (12)^2
\]
\[
= 3.14 \times 144
\]
To compute that:
\[
A = 3.14 \times 144 = 452.16
\]
Thus, the area of the circle is approximately \( 452.16 \) square feet.
The correct answer is:
d. 452.16 square feet
\[
A = \pi r^2
\]
where \( r \) is the radius.
