Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the values

Given \(d = 6\) inches and \(\pi\approx3.14\), then \(C=3.14\times6\).

Step3: Calculate the product

\(3.14\times6=(3 + 0.14)\times6=3\times6+0.14\times6=18 + 0.84 = 18.84\)

Answer:

B. \(C\approx18.84\) in
