Question

Find the height of cone of diametet 10cm and slant height 13cm

Answer 1

Answer:

$\large\boxed{\sf{12\;cm}}$

Step-by-step explanation:

Diameter of the cone = 10 cm

.°. Radius , r = 5 cm

Slant height, l = 13 cm

Let, the height be 'h' cm

Therefore, we have,

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

Hence, Height of cone is 12 cm
