Which of the following is a correctly balanced equation? A. NaClO3 → NaCl 3O2 B. 2HgO → 2Hg O2 C. 2ZnS O2 → 2ZnO 2SO2 D. 4CO Fe3O4 → 4CO2 Fe E. 2Fe 2Cl2 → 2FeCl3.

The figures Cone Z and Cylinder Y have the same volume.

Explanation:

The volume of the cylinder is given by

The volume of the cone is given by

It is given that, "Cone Z has the same base area as cylinder Y, but its height is three times the height of cylinder Y".

Hence, substituting in the volume formula of the volume of the cone.

We get,

Volume of cone Z =

Cancelling the common term, we get,

Volume of cone Z =

Volume of cone Z = Volume of the cylinder Y

Thus, the volume of the cone Z = volume of the cylinder Y

Therefore, the figure cone Z and cylinder Y have the same volume.
