Question

A circular swimming pool has a radius of 28 ft. There is a path all the way around the pool that is 4 ft wide. A fence is going to be built around the outside edge of the pool path

Answer 1

201

Explanation:

assuming we are finding the circumference of the outer circle or the path to find the length of the fence we start by combining the radius of the pool and the path width for the radius of the second circle around the first one. the circumference or C is equal to 2
`\pi` x the radius or r you can also use the diameter or d, times
`\pi` for the circumference

with this info we can figure out the answer

lets say
`\pi` = 3.14

32 = r

r x 2 = d

d x
`\pi` = 200.96 rounded its 201

the circumference is 201
