Question

the radius of a circle is 7 meters. what is the circumference?
give the exact answer in simplest form.
meters

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given radius into the formula

Given \(r = 7\) meters. Substitute \(r=7\) into \(C = 2\pi r\), we get \(C=2\pi\times7\).

Step3: Simplify the expression

\(C = 14\pi\)

Answer:

\(14\pi\)
