Find for cone Radius=3 and Slant Height=5. Find Volume

Solution:
Your problem `->` for cone Radius=3 and Slant Height=5. Find Volume


`"Here, we have Radius "(r) = 3" and Slant Height " (l) = 5" (Given)"`

`l^2 = r^2 + h^2`

`h^2 = l^2 - r^2`

`h^2 = 5^2 - 3^2`

`h^2 = 16`

`h = 4`


`"Volume" = (pi r^2 h)/3`

`=(22/7 * 3^2 * 4)/3`

`=37.7143`


`"Total Surface Area" = pi r (l + r)`

`=22/7 * 3 (5 + 3)`

`=75.4286`


`"Curved Surface Area" = pi r l`

`=22/7 * 3 * 5`

`=47.1429`
