Solid Geometry Continues....

Now back with another shape called as torus which deals with ring ball types objects. It is exactly looking like ring ball we used to play with in schools.

This torus has also some important properties which is listed below.

• It can be made by revolving a
  small circle (radius r) along a line made
  by a bigger circle (radius R).
• It has no edges or vertices
• It is not a polyhedron

Torus also haves volume and surface area which we can't deny.  Here follows the image of torus. These images are taken from google and matter referred from various websites
