Answer 2

Answer:

12 is the height of cone.

Step-by-step explanation:

Given =

slant height of cone = 13cm

Radius of cone = 5cm

A.T.Q

To find =

height of cone(h) = ?

$l = \sqrt{ {r}^{2} + {h}^{2} } \\ h = \sqrt{ {l}^{2} - {r}^{2} } \\ h = \sqrt{ {13}^{2} - {5}^{2} } \\ h \: = \sqrt{169 - 25} \\ h \: = \sqrt{144} \\ h = 12cm \:$
