WebJun 26, 2015 · The cup is in the shape of a Conical Frustum. If the cup has a radius of $r_1$ at the bottom and $r_2$ at the top and a height of $h$, then its volume is $V = … WebJun 26, 2015 · If the cup has a radius of r 1 at the bottom and r 2 at the top and a height of h, then its volume is V = 1 3 π h ( r 1 2 + r 1 r 2 + r 2 2). You can derive this formula without any calculus if you know the formula for the volume of a cone. In the diagram above, the volume of the frustum is the volume of the large cone minus the volume of the ...
