To find 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.
Given that the radius \(r\) is 2.5 feet, we can substitute that into the formula:
\[ C = 2 \times 3.14 \times 2.5 \]
Calculating this:
\[ C = 2 \times 3.14 \times 2.5 = 15.7 \]
Thus, the circumference of the circle is approximately 15.7 feet.
The correct response is:
15.7 feet
