Complete question :
A circular swimming pool has a radius of 28 ft. There is a path all around the pool that is 4 ft wide. A fence is going to be built around the outside edge of the pool path.
About how many feet of fencing are needed to go around the pool path
Answer:
201 feets
Explanation:
The Circumference of a circle, C :
C = 2 * pi * r
r = Radius ; pi = 3.14
The entire Radius = pool radius + pathnaroind the pool = 28 + 4 = 32
Hence, the Circumference, which gives the value of fencing required is :
C = 2 * 3.14 * 32
C = 200.96 ft
C = 201 feets
