Question

A circular pool has a radius of 6 ft. What is the approximate circumference of the pool?

A. 19 ft
B. 38 ft
C. 113 ft
D. 452 ft

Answer 1

Answer: Option B. 38 ft

Explanation:

To find the circumference of a circle, we use the formula C = 2πr, where C represents the circumference, r represents the radius of the circle, and π (pi) is a mathematical constant that is approximately equal to 3.14.

In this problem, we are given that the radius of the circular pool is 6 ft. We can substitute this value into the formula to find the circumference:

C = 2πr

C = 2π(6)

C ≈ 37.7 ft

Therefore, the approximate circumference of the pool is 37.7 feet. This is closest to answer choice B, which is 38 ft.

Answer 2

Circumference = 2πr;
r = 6 ft. => C = 2π • 6 ≈ 37.7 ≈ 38 ft.
Answer: B 38 ft.
