Formula: Frustum of a Circular Right Cone Volume Height Radius of the base Radius of the upper area
$$V ~=~ \frac{\pi \, h}{3} \, \left( {\class{red}{r_1}}^2 ~+~ {\class{blue}{r_2}}^2 ~+~ \class{red}{r_1} \, \class{blue}{r_2} \right)$$
$$V ~=~ \frac{\pi \, h}{3} \, \left( {\class{red}{r_1}}^2 ~+~ {\class{blue}{r_2}}^2 ~+~ \class{red}{r_1} \, \class{blue}{r_2} \right)$$
$$h ~=~ \frac{ 3V }{ \pi \, \left( {\class{red}{r_1}}^2 + {\class{blue}{r_2}}^2 + \class{red}{r_1} \, \class{blue}{r_2}\right) }$$
