The best app to calculate all quantities of a frustum of a cone. You must enter some quantities like the radius and a height. The algorithm searches the formulas of the missing quantities, shows them and calculates the results.

The length of the decimal place can be changed. The algorithm shows when rounding or wrong values lead to an opposition.

Decimals and fractions are supported. The solution is shown step by step. All calculations are stored in the history. The final solution can be shared.
