Question

Keisha swims 18 ft from one side of her circular pool to the other, swimming straight through the center. She then swims one time around the entire edge of her swimming pool.

Use 3.14 for π

Round your answer to the nearest tenth.

____ ft

Answer 1

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:

$c = \pi \: d$

where d=18 is the diameter and π=3.14 as given.

We substitute the values to get:

$c = 3.14 \times 18$

$c = 56.52$

We approximate to the nearest tenth to get:

$c = 56.5ft$
