To find the circumference of a circle, you can use the formula:
\[
C = \pi d
\]
where \( C \) is the circumference and \( d \) is the diameter of the circle.
Given that the diameter \( d = 6 \) feet, we substitute the diameter into the formula:
\[
C = \pi \times 6
\]
Using the approximation \( \pi \approx 3.14 \):
\[
C \approx 3.14 \times 6 = 18.84 \text{ feet}
\]
Therefore, the circumference of the circle is approximately \( 18.84 \) feet.
If you were to use a more precise value for \( \pi \), you would simply leave the answer in terms of \( \pi \):
\[
C = 6\pi \text{ feet} \approx 18.84 \text{ feet}
\]
Thus, the final answer for the circumference of the circle is:
\[
\boxed{18.84} \text{ feet}
\]
\[
C = \pi d
\]
where \( C \) is the circumference and \( d \) is the diameter of the circle.
