To find the circumference of a circle, you can use the formula:
\[
C = \pi \times d
\]
where \( C \) is the circumference and \( d \) is the diameter of the circle.
Given that the diameter is 4 feet:
\[
C = \pi \times 4
\]
Using the approximation \( \pi \approx 3.14 \):
\[
C \approx 3.14 \times 4 = 12.56 \text{ feet}
\]
Rounding this to the nearest whole number gives us approximately 13 feet.
Therefore, the best estimation for the circumference is **13 feet**.
