Question

Rachel is putting up a fences around her pool. The pool has a diameter of 12 feet.How many feet of fencing will she need to go around the sidewalk?

Answer 1

Since we are told the pool has a diameter of 12 feet, we assume it is a round pool

So, in order to find how may feet of fencing are needed, we need to calculate the circumference of a circle

$C=\pi\cdot d$

Where d is the diameter in feet

Therefore,

$C=12\pi=37.699\cong37.7$
