A machine is rolling a metal cylinder under pressure. The radius of the cylinder is decreasing at the rate of
0.05cm per second and the volume V is 128pie cu.cm. At what rate is the length "h" changing when the radius is 2.5 cm.
let r be radius , and V be volume of cylinder . h is length of cylinder volume of cylinder , V = r 2 h = 125 ... View the full answer
