Answer:

39.27 feet.

Explanation:

We are asked to find the fence needed to enclose a pool with a diameter of 12.5 feet.


\text{Circumference of circle}=\pi D, where D represents diameter of circle.


\text{Circumference of circle}=\pi* \text{12.5 feet}


\text{Circumference of circle}=39.2699\text{ feet}


\text{Circumference of circle}\approx 39.27\text{ feet}

Therefore, 39.27 feet of fence is needed to enclose the pool.

Answer:


12.5 \pi\ ft or
39.25\ ft

Explanation:

we know that

The circumference of a circle is equal to


C=\pi D

In this problem we have


D=12.5\ ft

substitute


C=\pi (12.5)=12.5 \pi\ ft

assume
\pi =3.14


12.5 \pi\ ft=39.25\ ft
