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**
\[
C = \pi \times d
\]
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**
