Question #N788
A circle has a radius of 5 cm. What is the circumference of the circle? (Use $\pi = 3.14$)
A. 15.7
B. 31.4
C. 62.8
D. 157
Correct Answer is: B
The circumference of a circle is given by the formula $C = 2\pi r$, where $r$ is the radius. Substituting the given values, we get $C = 2(3.14)(5) = 31.4$.
