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

Given the statement:

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.

Determine the circumference of the outer edge.

Formula for the circumference of the circle:

C = 2 pi r

Solution:
Since it is stated that we need to determine the circumference of the outer edge, then we simply take the radius of the outer edge of the circle which is 15 ft and substitute it to the formula for the circle

C = 2 pi r

C = 2 ( 3.14) ( 15 ft )

C = 94.2 ft

Final answer:

The circumference of the circle is 94.2 ft
