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%2Ar%5E2%2Ah
where
r = the radius
h = the height
:
The formula for volume of a cone is similar:
V = 1%2F3*pi%2Ar%5E2%2Ah
to find the height if you know the radius and the volume of a cone, solve for h
1%2F3*pi%2Ar%5E2%2Ah = V
multiply both sides by 3
pi%2Ar%5E2%2Ah = 3V
Divide both sides by pi%2Ar%5E2
h = %283V%29%2F%28%28pi%2Ar%5E2%29%29

"then how would you find the length if you know the height and volume.
the length of cylinder would be height:
h = V%2F%28%28pi%2Ar%5E2%29%29
