The meaning of a circumference is around the circle.To find the circumference you use a formula which is 2piR. The pi part is pretty much a line on top and two lines on the bottom and one of the line is curved at the bottom(the one to the left). It represents 3.14. The R is the radius which is half of the diameter. The 2 is just stands for times by 2. All you do then is to times 2 and 3.14 and 5.Below are the steps you follow.
STEPS
1) USE THE FORMULA 2PIR(2 PI R)
2) THEN TIMES 2 AND 3.14 AND 5.(PI=3.14)
ANSWER=31.4FT

2r times pi.
31.4 feet.
the radius is half of the diameter. the radius is 5, so diameter is 10. pi is defined as the ratio of circumference to diameter in a circle.
In other words, a circle is 3.14 times longer around than it is wide.
3.14 times 10 = 31.4

double the diameter 5=10
times 10 by pi
something like 31.4 ....

simple 5x2=10 that's to find the diameter then multiply by pi, 3.14
your answer is 31.4 ft.

c=2pi*r
c=2*3.14*5=10*3.14=31.4 feet
