Give only relevant answer otherwise will be reported///

if slant hright of cone is 3m then find radius and height of cone//

Answer 1

hey mate here is your answer

Given l = 3m

$l^{2} =h^{2} +r^{2}$

Let radius be r  and hright be h

$r^{2}= 9-h^{2}$

we know

Step-by-step explanation:

hey mate here is your answer

Given l = 3m

$l^{2} =h^{2} +r^{2}$

Let radius be r  and hright be h

$r^{2}= 9-h^{2}$

we know

volume = $\frac{1}{3} *3.14*r^{2}*h </p><p>]V_{max} = \frac{d(\frac{1}{3}*3.14*9-h^{2} ) }{dt} =0$

                    = $d\frac{(9h-h^{3)} }{dt} =0$

  $9-3h^{2} =0$                  

            $3h^{2} =9$

            $h^{2} = 3$

             $h=\sqrt{3}$

And  $r=\sqrt{6}$
