which is closer to the circumference of the fence they will need?

Question

a circular swimming pool has a redious of 15 feet. the family that owens the pool wants to put up a circular fence that is 5 feet away from the pool at all point.

Answer 1

The circumference is defined by the formula:

 

C = 2 (pi) (radius)

 

Here for the fencing, the radius will be 15 + 5 = 20 feet

Then the circumference for the fencing is

 

C = 2(3.14)(20)

 C = 125.6 feet

 

This is an approximate answer since we are using 3,14 as approx for pi
