How to use this Cone Slant Height Calculator 🤔

Enter ✎ value for radius (r).
Enter ✎ value for height (h).
As soon as you enter the required input value(s), the Cone Slant Height is calculated immediately, and displaed in the output section (present under input section).

Formula

To calculate the cone slant height, you can use the following formula.

\(l = \) \( \sqrt{ r ^2 + h ^2 } \)

where

Calculation

Once you enter the input values in the calculator, the output parameters are calculated.
