circular pool w/ circumference of 23 ft. Pool is surrounded by a fence 2.5 ft apart from edge of the pool. What is the circumference of the fence?

Given the circumference of the pool is 23
feet.

Let us calculate the
radius.

==> C = 2* r *
pi

==> 23 = 2*r *
pi

==> r= 23/2pi = 3.66
ft

Now we need to determine the circumference of the
fence.

First lest determine the
radius.

We know that the radius is the pool is
3.66

Also, the fence is 2.5 ft from the
pool.

Then the radius of the fence is 3.66 + 2.5 =
6.16

Now we will calculate the
circumference.

==> C = 2* r * pi = 2* 6.16 * pi =
38.708 ft

Then the circumference of the fence
is 38.708 ft.
