Formula for surface area (S) of a sphere is = constant Factor of Pai (22/7=3.142) R * Spheres Periopheri. Where R is the Radius of the sphere.

For a sphere of radius R, the surface area is 4* (pi) * R^2. (the product of 4 pi times the square of the radius of the sphere)

The surface area of a sphere is given by the following formula A=4"r2 This formula was first derived by Archimedes, based upon the fact that the projection to the lateral surface of a circumscribing cylinder (i.e. the GallPeters map projection) is areapreserving. It is also the derivative of the formula for the volume with respect to r because the total volume of a sphere of radius r can be thought of as the summation of the surface area of an infinite number of spherical shells of infinitesimal thickness concentrically stacked inside one another from radius 0 to radius r. At infinitesimal thickness the discrepancy between the inner and outer surface area of any given shell is infinitesimal and the elemental volume at radius r is simply the product of the surface area at radius r and the infinitesimal thickness. http://anu0562.blogspot.com/…
