Question

the radius of a circle measures 16 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 \(r = 16\) ft and \(\pi=3.14\), substitute into the formula: \(C = 2\times3.14\times16\).
First, calculate \(2\times16 = 32\). Then, \(C=3.14\times32\).

Step3: Perform the multiplication

\(3.14\times32=(3 + 0.14)\times32=3\times32+0.14\times32=96 + 4.48 = 100.48\).

Answer:

\(100.48\) ft
