WebJan 29, 2024 · The perimeter of a circle can be determined one of two ways: C = pd. C = p2r. wherein C - circumference, d = diameter, r i= radius (which is half of the diameter), and p = Pi, which equals 3.1415926. Use Pi to find the perimeter of a circle. Pi is the ratio of a circle's circumference to it's diameter. If the diameter is 1, the circumference is pi. how to spell epilepticWebCircumscribing regular polygons around the unit circle will overestimate the value of π, and therefore using these methods with circumscribed polygons will generate areas that approach π from above. ...
