The circumference \( C \) of a circle can be calculated using the formula:

\[
C = \pi \times d
\]

where \( d \) is the diameter of the circle. Given that the diameter is 4 feet:

\[
C = \pi \times 4
\]

Using \( \pi \approx 3.14 \):

\[
C \approx 3.14 \times 4 \approx 12.56 \text{ feet}
\]

Therefore, the best estimation for the circumference is approximately 13 feet.

So the correct response is:

**13 feet**
