Use this circular calculator to determine the area, circumference, radius or diameter of a circle. For each variable A, C, r or d in a circle, you can count the other three unknowns.

* Units: Please note that units of length are displayed for the sake of simplicity. They have no influence on calculations. Units are available to indicate the order of results, e.g. B. ft, ft2 or ft3. Any other base can be replaced.

The circular formula is related to Pi π, radius r and diameter d
Radius and diameter:
r = d / 2
d = 2r

County area:
A = πr2 = πd2 / 4

circumference:
C = 2πr = πd

Circle of Calculation:
With the formula above and additional formulas, you can calculate circle properties for each variable.
