This sphere calculator can help you calculate the volume, area, diameter, circumference or the radius of a sphere if you provide only one out of the 5 dimensions.

I want to input:*

## How does this sphere calculator work?

The algorithm of this sphere calculator requires only one dimension to be given and that can be the radius, diameter, area or the volume; while the formulas applied are explained below:

Diagonal (d) = 2r

Area (A) = 4πr2

Volume (V) = 4/3πr3

Circumference (C) = r

In case the radius (r) is provided then the above formulas should be used.

If the diagonal (d) is the known variable then first you have to figure out the radius then compute the other 3 dimensions (C, A & V).

If the circumference (C) is known then first you have to determine the radius as r = C / 2π, then you can find the other 3 dimensions (d, A & V).

In case the area (A) is the given figure then r = √(A / 4π). Once the radius is calculated the other figures (d, C & V) can be obtained by using the same standard equations explained.

Finally if the volume (V) is given then r = Cuberoot(3V / 4π) and the other dimensions (d & A) can be then calculated as well.
