To calculate the circumference of a circle, you can use the formula:
\[
C = 2\pi r
\]
where \(C\) is the circumference, \(\pi\) is approximately 3.14, and \(r\) is the radius of the circle.
Given that the radius \(r\) is 3 feet, we can substitute this value into the formula:
\[
C = 2 \times 3.14 \times 3
\]
Now let's perform the calculation:
1. First, calculate \(2 \times 3.14\):
\[
2 \times 3.14 = 6.28
\]
2. Next, multiply this result by the radius (3):
\[
6.28 \times 3 = 18.84
\]
Therefore, the estimated circumference of the circle is:
\[
\boxed{18.84} \text{ feet}
\]
