The formula for the circumference \( C \) of a circle is given by:
\[ C = 2 \pi r \]
Where \( r \) is the radius. For a circle with a radius of 2.5 feet and using \( \pi \approx 3.14 \):
\[ C = 2 \times 3.14 \times 2.5 \]
Calculating:
\[ C = 2 \times 3.14 = 6.28 \] \[ C = 6.28 \times 2.5 = 15.7 \]
So, the estimated circumference rounded to the tenths place is:
\[ \text{Circumference} \approx 15.7 \text{ feet} \]
The correct response is 15.7 feet.
