Explanation:

Step1: Recall the formula for the circumference of a circle

The formula for the circumference of a circle is $C = \pi d$, where $d$ is the diameter and $\pi\approx3.14$.

Step2: Substitute the given diameter

Given $d = 7$ feet and $\pi = 3.14$, we have $C=3.14\times7$.
$C = 21.98\approx22$ feet.

Answer:

B. 22 feet
