Question #N156
A circle has a radius of 5. What is the circumference of the circle? (Use 3.14 for pi)
A. 15.7
B. 31.4
C. 78.5
D. 157
Correct Answer is: B
The circumference of a circle is found using the formula C = 2πr, where C is the circumference, π (pi) is approximately 3.14, and r is the radius. Substituting the given values, we get C = 2 * 3.14 * 5 = 31.4.
