Enter Value
A circle, geometrically, is a simple closed shape. More specifically, it is a set of all points in a plane that are equidistant from a given point, called the center. It can also be defined as a curve traced by a point where the distance from a given point remains constant as the point moves.
Circle Formulas
- Diameter: `d = 2 * r`
- Circumference: `C = 2 * π * r = π * d`
- Area: `A = π * r²`
