The Sphere

The following elements of a sphere are calculated if one of the first five is given. Additionally calculated are the radius and the perimeter of a parallel circle with a given central angle.

Example:

Given:
¯¯¯¯¯¯
      Surface S = 1

Results:
¯¯¯¯¯¯¯   
        Radius r = 0,28209479
    Diameter d = 0,56418958
   Perimeter p = 1,7724539
      Volume V = 0,094031597

Parallel circle :   48°
       Radius r' = 0,18875826
  Perimeter u' = 1,1860031
