Mensuration Formula Connecting the Volumes of Hemisphere, Cone, Spherical Sector and Great Cone

In this article, we introduce a very nice relationship between n times volume of hemisphere, volume of ā€˜nā€™ number of circular cones with spherical sector or shell and a great cone with base radius as that of the given sphere and height as the sum of the heights of the above ā€˜nā€™ number of inscribed cones. In other words, the difference between n times the volume of hemisphere with radius R and the sum of volumes of n number of cones with spherical sector or shell is equal to twice the volume of the great cone. Key words- Spherical sector or shell, volume of great cone, great height (H), great radius, non over lapping cone bases.
