The circumference of the outer edge of the path around the pool is 113.04 ft.
<h3>
What is the circumference?</h3>
The Circumference (or) perimeter of circle = 2πR. where, R is the radius of the circle.
Given
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.
The radius of the outer edge of the path around the pool = Radius of circle + width of outer circle.
The radius of the outer edge of the path around the pool = 15 + 3
The radius of the outer edge of the path around the pool = 18ft
The circumference of the outer edge of the path around the pool is;
![\rm Circumference=2\pi r\\\\Circumference = 2\times 3.14 \times 18\\\\Circumference=113.04 \ ft](https://tex.z-dn.net/?f=%5Crm%20Circumference%3D2%5Cpi%20r%5C%5C%5C%5CCircumference%20%3D%202%5Ctimes%203.14%20%5Ctimes%2018%5C%5C%5C%5CCircumference%3D113.04%20%5C%20ft)
Hence, the circumference of the outer edge of the path around the pool is 113.04 ft.

Ok so to solve for percent off
percent off means discount
so therefor we need to find how much was discounted
30-20.10=9.90
so we see that 9.90 was discounted
to find the percent we do
discount/total=percent discount
9.90/30=0.33
percent means parts out of 100
0.33/1 times 100/100=33/100=33%
answer is 33% discout
