Question #N559
A circle has a radius of 5 units. What is the area of the circle, in square units?
A. 5\pi
B. 10\pi
C. 25\pi
D. 100\pi
Correct Answer is: C
The area of a circle is given by the formula $\pi r^2$, where $r$ is the radius. Since the radius is 5 units, the area of the circle is $\pi (5)^2 = 25\pi$ square units.
