Question

The Height Of A Cone Is $16 c m$ And Its Base Radius Is $12 c m$ $(π = 3.14)$ . Find Its Slant Height.

Open in App

Solution

Slant Height of cone
$l = \sqrt{h^{2} + r^{2}} l = \sqrt{16^{2} + 12^{2}} l = \sqrt{256 + 144} l = \sqrt{400} l = 20 c m$
Therefore, the slant height of the cone is $20 c m .$
