Question

Find l of the following cone ​

Answer 1

Answer:

$l = \sqrt{261}\: in$

Step-by-step explanation:

Height of the cone h = 15 in

Radius of the cone r = 12/2 = 6 in

We need to find slant height (l) =?

$\because l = \sqrt{ {r}^{2} + {h}^{2} } \\ \\ \therefore l = \sqrt{ {6}^{2} + {15}^{2} } \\ \\\therefore l = \sqrt{36 + 225} \\ \\\therefore l = \sqrt{261}$

Answer 2

Answer:

l = √261 in

Step-by-step explanation:
