Answer
The circumference of the pool is $31.4 ft$.
Work Step by Step
The circumference of a circle is given by the following formula:
$C = \pi(d)$,
where $C$ is the circumference and $d$ is the diameter of the circle.
We know that the diameter of a circle is $10 ft$, so let us set up the equation:
$C = \pi(10 ft)$
Multiply to solve for $C$:
$C = 31.4 ft$
