Question

what is the circumference of a circle with a diameter of 5 feet? use 3.14 for π. a. 7.85 ft b. 15.7 ft c. 31.4 ft d. 8.14 ft

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 given values

Given \(d = 5\) feet and \(\pi=3.14\), we substitute into the formula: \(C=3.14\times5\).

Step3: Calculate the result

\(3.14\times5 = 15.7\).

Answer:

B. \(15.7\) ft
