The formula for the volume of a cylinder is V = πr2h. The volume of a cylinder is three times the volume of a cone with the same radius and height.
If the volume of a cone with the same height as a cylinder equals the volume of the cylinder, the equation for the radius of cone R in terms of the radius of cylinder r is

Question

The formula for the volume of a cylinder is V = πr2h. The volume of a cylinder is three times the volume of a cone with the same radius and height.
If the volume of a cone with the same height as a cylinder equals the volume of the cylinder, the equation for the radius of cone R in terms of the radius of cylinder r is

unklerhaukus · Answer

what do you get for the equation of a cone of radius r and height h

anonymous · Answer

all i got is this.... 1/3 (Pi) h

unklerhaukus · Answer

any r's ? in that formula?

anonymous · Answer

Yes, R= Radius

unklerhaukus · Answer

you should have     1/3 (Pi) R^2 h
