Question #N863
A circle has a radius of 5. What is the circumference of the circle?
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. In this case, $r = 5$, so the circumference is $C = 2\pi (5) = 10\pi$.
