Program to find the surface area of the sphere

The sphere can be defined as the round 3D object having a string of points located at a uniform distance from a particular point called center. It is perfectly symmetrical and has no edges or vertices.

A sphere with radius r has a volume of (4/3) x pie x radius2 and a surface area of 4 x pie x r2.

Formula

Surface area of sphere =   4 x pie x r2

Algorithm

  1. Define the radius of the sphere.
  2. Define the value of pie.
  3. Calculate the surface area of the sphere by 4 x pie x (radius x radius).
  4. Define surface_sphere and assign the surface area of the sphere to it.

Complexity

O(1)
