Question #N1017
A circle has a radius of 5 cm. What is the area of the circle in square centimeters? (Use $\pi$ = 3.14)
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. Substituting 5 for $r$ and 3.14 for $\pi$, we get $A = 3.14 * 5^2 = 3.14 * 25 = 78.5$ square centimeters.
