Explanation:

Step1: Recall the formula for circumference

The formula for the circumference of a circle is \(C=\pi d\), where \(d\) is the diameter.

Step2: Substitute the given diameter

Given \(d = 3\) feet and using \(\pi\approx3.14\), we have \(C=3.14\times3\).

Step3: Calculate the value

\(C = 9.42\) feet.
