Question #N950
A circle has a radius of 5. What is the circumference of the circle? (Express your answer in terms of *pi*)
A. 5*pi
B. 10*pi
C. 25*pi
D. 50*pi
Correct Answer is: B
The circumference of a circle is given by the formula C = 2 * pi * r, where r is the radius. Substituting 5 for r, we get C = 2 * pi * 5 = 10*pi.
