How does the volume of a cone compare to the volume of a cylinder with the same radius and height?

To answer this question, you need to know the formula for calculating the volume of cone and cylinder. The formula should look like this:

cone volume: π * r^2 * h/3
cylinder volume: π * r^2 * h

Now if you compare both of them with information that the radius and height is same, then the cone:cylinder volume ratio would be:

Cone volume/cylinder volume=
π * r^2 * h/3 / π * r^2 * h= 1/3

Cone volume is 1/3 of cylinder volume

The answer is b: step 2.
