Question

A small swimming pool has a circumference of 3π feet. Select the true statement about the pool.

a
The radius is 3 ft.
b
The diameter is 3 ft.
c
The diameter is 1.5 ft.
d
The radius is 6 ft.

Answer 1

The answer to your question is the letter B. the diameter = 3 ft

Explanation:

Data

Circumference = 3π feet

The Circumference is defined as the distance around the edge of a circle.

Formula

Circumference = 2πr

Process

1.- Equal the value of the circumference to the formula

2πr = 3π

2.- Solve for r

r = 3π / 2π

3.- Simplification

r = 3/2 or 1.5 ft

4.- Calculate the diameter

diameter = 2 x radius

diameter = 2(1.5)

= 3 ft
