This online calculator will calculate the various properties of a conical frustum given the 2 radii and any 1 other known variable. This geometric solid conical frustum is one of a cright circular cone, where a right cone is a cone with its vertex point above the center of its base. The frustum is a cone with the top cut off by making a slice parallel to the base.
Note that frustum is often misspelled "frustrum".
* Units: Note that units are shown for convenience but do not affect the calculations. The units are in place to give an indication of the order of the results such as ft, ft^{2} or ft^{3}. For example, if you are starting with mm and you know r and h in mm, your calculations will result with s in mm, V in mm^{3}, L in mm^{2}, T in mm^{2}, B in mm^{2} and A in mm^{2}.
Below are the standard formulas for a conical frustum. Calculations are based on algebraic manipulation of these standard formulas.
Use the following additional formulas along with the formulas above.
