On this page, we're looking at spheres! Not only is this a sphere volume calculator, it will also calculate sphere surface area, double trouble!
A sphere is a geometrical object, a three-dimensional counterpart of a two-dimensional circle. It is defined as the set of points in three-dimensional space equidistant from a given point, known as the sphere's centre, with a radius denoted by 'r.'
The sphere surface area calculator and sphere volume calculator will use these basic geometry principles in their determination.
