Question

How to find slant height. What is the formula?

Answer 1

Find the formula for Slant Height:

${\mathrm{c}}^2={\mathrm{a}}^2+{\mathrm{b}}^2$

$\mathrm{c}=$slant height.

$\mathrm{a}=$an altitude of the surface (axis).

$\mathrm{b}=$distance from the center of the base to the point where the slant height segment starts (radius).

Therefore slant height is ${\mathrm{a}}^2+{\mathrm{b}}^2$.
