Answer:

94 feet

Explanation:

Determine the radius: The pool is 30 feet wide, so the radius is half of that, which is 30/2 = 15 feet.

Calculate the circumference: Use the formula Circumference = 2πr, where π is approximately 3.14159 and r is the radius you found in step 1. Multiply 2 by π and then by the radius.

Circumference = 2 * 3.14159 * 15

Evaluate the expression: Multiply 2 by 3.14159 and then multiply the result by 15.

Circumference ≈ 94.2477 feet

Round to the nearest whole foot: Since we want the answer to the nearest whole foot, round the calculated circumference to the nearest whole number.

Rounded circumference ≈ 94 feet
