Question #N753
A circle has a circumference of 12\pi. What is the radius of the circle?
A. 3
B. 6
C. 12
D. 24
Correct Answer is: B
The circumference of a circle is given by the formula C = 2\pi r, where C is the circumference and r is the radius. We are given that C = 12\pi. Substituting 12\pi for C in the formula gives 12\pi = 2\pi r. Dividing both sides of this equation by 2\pi gives 6 = r. Therefore, the radius of the circle is 6.
