A circular swimming pool has a radius of 15 ft. There is a path all the way around that pool that is three feet wide. A circle has a radius of 15 feet. A larger circle goes around the smaller circle that is 3 feet wide. What is the circumference of the outer edge of the path around the pool? Use 3.14 for Pi. 56.52 ft 94.20 ft 113.04 ft 114.04 ft

113.04ft

Step-by-step explanation:

Radius of circle + width of outer circle

15 + 3 =18ft

Circumference of the outer edge becomes

2 × 3.142 × 18

=113.04ft
