Question #N107

A circle has a diameter of 10 inches. What is the circumference of the circle, in inches? (Use 3.14 for \(\pi\)).
A. 15.7
B. 31.4
C. 62.8
D. 157

Correct Answer is: B

The circumference of a circle is given by the formula \(C = \pi d\), where \(C\) is the circumference and \(d\) is the diameter. Substituting 10 for \(d\) and 3.14 for \(\pi\) gives \(C = (3.14)(10) = 31.4\).
