Question

the radius of a circle is 5 miles. what is the circumference?
give the exact answer in simplest form.
miles

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 radius

Given \(r = 5\) miles. Substitute \(r = 5\) into the formula: \(C=2\pi\times5\).

Step3: Simplify the expression

\(C = 10\pi\)

Answer:

\(10\pi\)
