Final answer:
The circumference of the circular swimming pool with a diameter of 18 feet is approximately 56.5 feet.
Step-by-step explanation:
To find the circumference of a circular pool, we use the formula:
Circumference = π * diameter
Given that the diameter of the pool is 18 feet, we can substitute this value into the formula:
Circumference = 3.14 * 18
Calculating this, we find that the circumference of the pool is approximately 56.52 feet. Rounding this to the nearest tenth, the circumference is 56.5 feet.
