Answer 1

The formula for the circumference \( C \) of a circle is given by:

\[ C = 2 \pi r \]

where \( r \) is the radius of the circle. Given that the radius \( r \) is 2.5 feet, we can calculate the circumference using \( \pi \approx 3.14 \):

\[ C = 2 \times 3.14 \times 2.5 \] \[ C = 6.28 \times 2.5 \] \[ C = 15.7 \text{ feet} \]

So, the estimated circumference to the tenths place is 15.7 feet.
