Consider a cone of cone of radius R and H Let a cone of height h is cut off from the top of ... A small coneis cut off at the top by a plane parallel to the base. If its volume be 1/27 of the volume of the given cone, then what is the height above the base ... Thus, the section of the cone is mode at a height of 20 cm above the base.
