Answer:
Circumference(C) of the circle is given by:

where, r is the radius of the circle.
As per the statement:
A circular swimming pool has a radius of 15 ft.
⇒radius of the pool(r) = 15 ft
There is a path all around that pool that is three feet wide.
⇒radius of the outer edge of the path around the pool(r') = 15 +3 = 18 ft
Substitute these in the formula we have;

⇒
Therefore, the circumference of the outer edge of the path around the pool is, 113.04 ft
