Question #N974
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 $r = 5$ cm and $\pi = 3.14$, we get $A = 3.14 \cdot 5^2 = 3.14 \cdot 25 = 78.5$ square centimeters.
