The volume is changing at a rate given by:
Step-by-step explanation:
Let's recall the formula for the volume of acone, since it is the rate of the cone changing what we need to answer:
Volume of cone =
where B is the area of the base (a circle of radius R) which equals =
and where H stands for the cone's height.
We apply the derivative over time operator () on both sides of the volume equation, making sure that we apply the rule for the derivative of a product:
