Question #N918
A circle has a radius of 5 centimeters. What is the area of the circle, in square centimeters? (Use 3.14 for $\pi$)
A. 15.7
B. 31.4
C. 78.5
D. 157
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. In this case, the radius is 5 centimeters. So, the area is $A = (3.14)(5^2) = (3.14)(25) = 78.5$ square centimeters.
