To find the circumference of a circle, we can use the formula:
\[
C = \pi \times d
\]
where \( C \) is the circumference and \( d \) is the diameter.
Given that the diameter \( d \) is 18 feet, we can substitute this value into the formula:
\[
C = \pi \times 18
\]
Using an approximate value for \(\pi \approx 3.14\):
\[
C \approx 3.14 \times 18 \approx 56.52 \text{ feet}
\]
Thus, the circumference of the circle is closest to 56.52 feet. The correct answer is:
**A. 56.52 feet**
\[
C = \pi \times d
\]
where \( C \) is the circumference and \( d \) is the diameter.
