Question 602781
how do you figure the height of cone, cylinder box if you know the diameter and radius.
:
The formula for the volume of a cylinder:
V = {{{pi*r^2*h}}}
where
r = the radius
h = the height
:
The formula for volume of a cone is similar:
V = {{{1/3}}}*{{{pi*r^2*h}}}
to find the height if you know the radius and the volume of a cone, solve for h
{{{1/3}}}*{{{pi*r^2*h}}} = V
multiply both sides by 3
{{{pi*r^2*h}}} = 3V
Divide both sides by {{{pi*r^2}}}
h = {{{(3V)/((pi*r^2))}}}
:
;
"then how would you find the length if you know the height and volume.
the length of cylinder would be height:
h = {{{V/((pi*r^2))}}}

Did this help you find your way?
