    Sphere
    A `sphere` is a symmetrical geometrical object. In non-mathematical usage, the term is used to refer either to a round ball or to its two-dimensional surface. In mathematics, a sphere is the set of all points in three-dimensional space (`R`3) which are at distance `r` from a fixed point of that space, where `r` is a positive real number called the `radius` of the sphere. Thus, in three dimensions, a mathematical sphere is considered to be a (two-...
