The radius of a cone is increasing at a rate of $3$ centimeters per second and the height of the cone is *decreasing* at a rate of $4$ centimeters per second.
At a certain instant, the radius is $8$ centimeters and the height is $10$ centimeters.
**What is the rate of change of the volume of the cone at that instant (in cubic centimeters per second)?**

*The volume of a cone with radius $r$ and height $h$ is $\pi r^2\dfrac{h}{3}$.*
