How Do You Figure Out The Perimeter Of A Circle?
Calculating the perimeter and area of shapes is a skill usually mastered in early middle school. There are formulas for figuring out the perimeter and area of every closed shape. Thankfully, the formulas for circles are some of the easiest to remember, and figuring out their perimeter, or circumference, is a cinch. This article will show you how–or refresh your memory, if you’ve been out of school for a while! Understand what “circumference” means. The circumference is the rim of an unrolled circle. It is identical in concept to the perimeter of another shape, such as a square. Simply put, it is the distance around the edge of the circle. Find the diameter. The diameter of a circle is the distance across it. You can find the diameter by locating the center of the circle, measuring from the center to the edge, and then doubling that number. Alternately, you can simply measure across the center of the circle. Multiply the diameter by Pi. Most math teachers will allow you to use 3.14 as
