Circle Calculator

Only one dimension of a circle is needed to be entered in order to see the corresponding values.

The circle calculator can quickly compute all mathematical variants of a circle simply by entering one of the circle elements. The process is fully automatic and will take a split second.

To calculate all mathematical possible solutions of a circle, the circle calculator solely requires one of the circle components. After inserting one component, the answer will be displayed very quickly because the process of carrying out calculations is completely automatic.

To calculate the area and spherical area of a circle it is only required to insert the values of the radius, circumference or diameter. Each factor of the circle will eventually have its own algebraic relation.

Circle Calculator


This calculator uses the following formulas:

Radius = Diameter / 2

Circumference of a circle = 2 × π × Radius

Surface area of a sphere = 4 × π × Radius 2

Area of a circle = π × Radius 2

Where π is the constant (3.141592654)
