To calculate the circumference of a circle, you can use the formula:
\[
C = 2 \pi r
\]
where \(C\) is the circumference and \(r\) is the radius. Given that the radius \(r\) is 2.5 feet and using \( \pi \approx 3.14\):
\[
C = 2 \times 3.14 \times 2.5
\]
First, calculate \(2 \times 2.5\):
\[
2 \times 2.5 = 5
\]
Now, multiply this by \(3.14\):
\[
C = 5 \times 3.14 = 15.7
\]
So the estimated circumference of the circle is \(15.7\) feet, rounded to the tenths place.

Yes, let's double-check the calculation step by step.
To find the circumference \(C\) using the formula \(C = 2 \pi r\), with \(r = 2.5\) feet and using \(\pi \approx 3.14\):
1. **Calculate \(2 \times 2.5\)**:
\[
2 \times 2.5 = 5
\]
2. **Now multiply by \(3.14\)**:
\[
C = 5 \times 3.14 = 15.7
\]
Thus, the calculated circumference of the circle is indeed \(15.7\) feet.
