Question #N822

A circle has a radius of 5 units. What is the area, in square units, of the circle?
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. Substituting r = 5 into the formula gives A = \pi (5)^2 = 25\pi.
