Question #N613
A circle has a radius of 5 centimeters. What is the circumference of the circle, in centimeters? (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 = 2Ï€r*, where *r* is the radius. Substituting 5 for *r* and 3.14 for *Ï€*, we get *C = 2(3.14)(5) = 31.4*.
