From the above formula, If we know the Surface Area of a sphere, then we can calculate the radius of a Sphere using the formula: The radius of a Sphere = âsa / 4Ï (Where sa is the Surface Area of a sphere). The mean curvature is the average of the two principal curvatures, which is constant because the two principal curvatures are constant at all points of the sphere. NOTE: The value of Ï can never be calculated exactly, so the surface area of a sphere is only a approximation. The surface area of a solid object is a measure of the total area that the surface of the object occupies.
