Question

the radius of a circle measures 5 ft. what is the circumference of the circle? use 3.14 for π, and do not round your answer. be sure to include the correct unit in your answer.

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference of a circle is \(C = 2\pi r\) (where \(r\) is the radius).

Step2: Substitute the given values

Given \(r = 5\) ft and \(\pi=3.14\), substitute into the formula: \(C=2\times3.14\times5\).

Step3: Perform the multiplication

First, \(2\times5 = 10\), then \(10\times3.14=31.4\).

Answer:

\(31.4\) ft
