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 $C$: $C = 31.4 ft$
