give the exact answer in simplest form.
meters

Explanation:

Step1: Write the formula for circumference

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

Step2: Substitute the value of radius

Given \( r = 8\) meters. Substitute \( r\) into the formula: \( C=2\pi\times8\).

Step3: Simplify the expression

\( C = 16\pi\).

Answer:

\(16\pi\)
