Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given diameter

Given $d = 7$ feet and $\pi=3.14$, we substitute into the formula: $C = 3.14\times7$.

Step3: Calculate the result

$C=21.98\approx22$ feet.

Answer:

B. 22 feet
