The volume V of a right circular cylinder of radius r and height h is V = Πr2h
1.) How is dV/dt related to drdt if h is constant and r varies with time? (Enter drdt as dr/dt.)
2.) How is dV/dt related to dhdt if r is constant and h varies with time? (Enter dhdt as dh/dt.)
3.) How is dV/dt related to dhdt and drdt if both h and r vary with time?
