Sphere Calculation

  • A sphere is an endless number of points equidistant from the centerpoint in a three-dimensional space

  • In three-dimensional space, the radius of a sphere is the segment connecting the center to any point on a sphere

  • The diameter is the longest distance between two points of the surface (2 · Radius)
