Answer:

We need approximately 201 ft of fencing

Step-by-step explanation:

We need to find the circumference of the pool plus the fence

C = 2*pi *r  where r is the radius of the pool and the fence

r = 28 +4 = 32

C = 2 * pi * (32)

C = 64 pi

Letting pi =3.14

C = 64*3.14

C =200.96 ft

Rounding to the nearest foot

We need approximately 201 ft of fencing

absor201

Answer:

201 feet

Step-by-step explanation:

Given:

radius=28 ft

path= 4 ft

radius + path= 28+4

                     =32

Circumference of circle= 2πr

c = 2 *π* 32

 = 200.9  

  =201!

201 feet of fencing are needed to go around the pool path!
