Question 901082
Circumference means all the way around a circle.
Circumference can be calculated by two equations: 
C=πd (Circumference equals Pi times the diameter) or 
C=2πr^2 (Circumference equals 2 times Pi times the radius squared)
For this problem I will use the first equation.
C=πd
C=3.14*5
C=15.7
There you go! The answer is 15.7 meters.
Hope that helped! :)
