The radius of a right circular cone is increasing at the rate of 6cm/sec while its altitude is decreasing
at 3cm/sec. Find the rate of change of its volume when its radius is 8cm and its altitude is 20cm.
@Mb551,
You should put all of these homework problems in a single post. You would also get more help if you started trying to do the problem yourself.
I don't like to do other people's homework.... but I am happy to help when you get stuck.
