To calculate 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 \( d = 4 \) feet, you can substitute this value into the formula:
\[ C = \pi \times 4 \]
Using the approximate value of \( \pi \) (around 3.14), we have:
\[ C \approx 3.14 \times 4 = 12.56 \, \text{feet} \]
Thus, the best estimation for the circumference of the circle would be **13 feet**.
