Truncated Cone!!!Hey, i need some help on the shape.....its basically a truncated cone, and i need to take 2 equation i.e the surface area formula being the one and the volume formula the other (volume is fixed to 600cm3). So i need to substitue volume equation in the surface area, by rearraning the height (h) in the volume, and putting in the h of surface area, if u get what i mean??? I havent got anyother values, only the volume, that being 600cm3.....please help guys. #2 20051120 07:53:46
Re: Truncated Cone!!!A truncated cone is basically a normal cone with the top cut off. That means that to find the volume, we need the radius of the top circle, the radius of the bottom circle and the height. If we only know one the height and the volume, then we cannot find the other two because it is two variables but only one equation. Why did the vector cross the road? It wanted to be normal. #4 20051120 22:46:32
Re: Truncated Cone!!!The volume of a truncated cone would be the volume of an untruncated cone minus the volume of the bit chopped off. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman
