Answer:
Swimming one time around the pool is 56.5 ft
Step-by-step explanation:
Swimming 18 ft from one side of her circular pool to the other, swimming straight through the center means the circular swimming pool has a diameter of d=18 ft.
The circumference of the circle is calculated using:
[tex]c = \pi \: d[/tex]
where d=18 is the diameter and π=3.14 as given.
We substitute the values to get:
[tex]c = 3.14 \times 18[/tex]
[tex]c = 56.52[/tex]
We approximate to the nearest tenth to get:
[tex]c = 56.5ft[/tex]
