    Finding the volume of a wine glass when placed on it's side - solids of revolution

    Apparently when a "snifter" glass is placed on it's side and filled up to the tip, this volume is the optimum amount that should be poured to make a shot.

    Hence i have put a glass on an axis and modelled an equation for the top half of the glass...

    f(x)= -0.00393x^4+0.0843x^3-0.693x^2+2.198x+1.246



    I know how to find the volume of the whole glass (using solids of revolution) which is 188mL (188cm^3), but i am unable to find a method for working out the volume when its tipped on its side and filled up (i.e) the region between the glass and the line g(x)=2.46

    So in effect my question is:

    "How do i work out the volume of the liquid that can be poured into this glass when it is placed on its side, using solids of revolution?

    If anyone could shed some light on the issue it would be greatly appreciated =) Thanks in advance =)

    Re: Finding the volume of a wine glass when placed on it's side - solids of revolutio

    You can't do it using solids of revolution because this is not a solid of revolution. In particular the top (or bottom in your picture) of the wine will be a flat surface, not curved.
