Conic Cylinder

A release-checked easy problem for training Uniform, Geometric Probability, Continuous Random Variables.

Question

A uniformly random point $(X,Y,Z)$ is selected from the interior of a cylinder whose base has radius $r$ and has height $h$. Assume the the base of the cylinder is centered at $(0,0,0)$. Find the probability that the point also lies within the cone whose base and height is the same as the cylinder.
