Question

A cylinder and a cone have the same diameter: 8 inches. The height of the cylinder is 9 inches. The height of the cone is 18 inches.

Use π = 3.14.

What is the relationship between the volume of this cylinder and this cone? Explain your answer by determining the volume of each and comparing them. Show all your work.

Answer 1

I know that the volume of the cylinder is V = 3.14r^2h and cone is V = 1/3 3.14r^2h

Answer 2

Then substitute the radius into the equation XD

Answer 3

Oh Okay, thanks! Let me go try to work this out.
