A cicumference is the perimeter or distance around the edge of a circle. To get the circumference you use the following equation: C=πd (3.1416 x diameter) where n = pi and is always 3.1416 Example: Say you have a circle with the diameter of 2 in. (diameter of circle)x(pi)= 2 in. x 3.1416 = 6.2832 So the circumference of a circle with a diameter of 2 in. is 6.2832 which means the circle is 6.2832 in. around the outside edge.

How to calculate diamter for a 10 foot tall column?
Measure the circumference of the column. Divide the circumference by "Pi" (3.1417) and the answer is the diameter. Example: If the circumference is 15", the diameter is 4.78", or 4 25/32"
