Question

Find l of the following cone ​

Answer 1

l = √261 in

Explanation:

Hope this helps

Answer 2

`l = √(261)\: in`

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 = √(36 + 225) \\ \\\therefore l = √(261) \\`
