The circumference of a circle is the distance around the outside edge of the circle. It is also sometimes referred to as the perimeter of the circle. As the image illustrates below, if we were to cut a circle, at a point around it’s circumference, and unfold it so that it becomes a flat line, the length of that line would be the length of the circumference. Knowing this information is useful when trying to find the right sling length to use, when rigging a pipe. Or when trying to calculate the weight of a pipe. To find the circumference of a circle we multiply Pie, times the diameter. Were pie is 3.1416 and the diameter is the distance across the circle passing through its center.
Circumference of a Circle
To find the circumference of a circle we multiply Pi times the diameter:
•Circumference of a Circle =π∗d
Where,
π (sounds like ‘pie’) is 3.1416 d is the diameter of the cylinder
