56.5 ft

Step-by-step explanation:

Here we know that:

- Keisha swims 18 feet from one side of her circular pool to the other swimming straight through the center --> this means that the diameter of the swimming pool is 18 feet, so

d = 18 ft

- Then, she swims one time around the entire edge of her swimming pool. --> this means that she swims along the perimeter of the swimming pool

The perimeter of a circle is given by

where d is the diameter. Therefore in this case, the length of Keisha's second swim is:
