Definition of a Sphere A sphere is a geometrical figure that is perfectly round, 3-dimensional and circular - like a ball. Geometrically, a sphere is defined as the set of all points equidistant from a single point in space.
Like a circle, which, in geometrical contexts, is in two dimensions, a sphere is the set of points which are all the same distance r from a given point in space. This distance r is known as the radius of the sphere, and the given point is known as the center of the sphere.
