What does it mean for the volume of a sphere to decrease at a constant rate?

Back

It means that the volume is reducing by the same amount every second, which can be expressed as a negative rate of change.

How do you find the rate at which water is being poured into a conical cup?

Back

Differentiate the volume formula with respect to time and substitute the known rates of change.

Front

What is related rates in calculus?

Back

Related rates involve finding the rate at which one quantity changes in relation to another quantity that is also changing.
