Question #N830
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 $A = \pi r^2$, where r is the radius of the circle. Since the radius of the circle is 5 units, the area of the circle is $A = \pi (5)^2 = 25\pi$ square units.
