Volume of Cone

Theorem
Let $K$ be a cone whose base is of area $A$ and whose height is $h$.

Then the volume of $K$ is given by:
 * $V_K = \dfrac {A h} 3$

Proof
Let $V_K$ be the volume of $K$.

Let $V_C$ be the volume of a cylinder of base $A$ and of height $h$.

From Volume of Cylinder:
 * $V_C = A h$

From Volume of Cone is Third of Cylinder on Same Base and of Same Height:
