The online calculator allows to calculate the volume of a sphere from its radius.

The calculator is able to calculate online the **volume of a sphere**, in other words, to calculate the
**volume of a ball**.
The **volume of a sphere** is given by the formula `4/3*pi*r^3` where r is the radius of the circle.
The volume calculator supports numeric but also literal expressions.

The volume calculator is able to calculate the volume of a sphere, from a numeric radius, the exact result and the approximate results are returned.

Thus, calculating the volume of a sphere of radius 3 is done by typing the following formula volume_sphere(`3`).

The volume calculator is able to do symbolic calculations in other words to do literal calculations. To calculate, for example, the volume of a sphere of radius 1 + x, you must enter the following formula volume_sphere(`1+x`), after calculating the result is returned.

volume_sphere(radius)

volume_sphere(`3`), returns `36pi`
