Question

A circular cone is being deformed in such a way that:
-Radius r is growing at a rate of 3 cm/s
-The volume V of the cone is kept constant.

At the time when the cone's radius is 11 cm and the height is 7 cm, what is the rate in cm/s at which the cone's height h decreases?

Comments:
-Volume of a circular cone of height h and radius r: V=πr2h/3.
-To avoid anguish in the interpretation of ``decrease/increase'' and the signs, the two possibilities are correct.
