### Volume of a sphere

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.

# Calculating the volume of a sphere

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).

# Symbolic computing the volume of a sphere

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.

#### Syntax :

volume_sphere(3), returns 36pi
