Understanding Sphere Radius Calculation

A sphere is a perfectly round geometrical object in three-dimensional space. The radius of a sphere is the distance from its center to any point on its surface. The volume of a sphere is the amount of space it occupies.

Formula

The volume (V) of a sphere is related to its radius (r) by the formula:

$$ V = \frac{4}{3} \pi r^3 $$

To calculate the radius (r) from the volume (V), we rearrange the formula:

$$ r = \sqrt[3]{\frac{3V}{4\pi}} $$
