Squaring the Circle - Calculator
Calculator for the edge length of a square and the radius of a circle, if both have the same area. Also the perimeter will be calculated. Squaring a circle geometrically is in fact impossible, a circle can't be constructed from a square and vice versa. Also the exact calculation can't be done, because the value of π (pi) can't be given exactly. But it can be calculated with an approximation at any accuracy.
If circle and square should have the same area, the edge length of the square has to be root-of-pi-times the circle radius,
Please enter one value, the other values will be calculated. Also pi can be entered or something like 2*pi.
