85129 A stone is dropped into a quiet lake and waves move in circles at the speed of \(6 \mathrm{~cm}\) per second. At the instant when the radius of the circular wave is \(12 \mathrm{~cm}\), the enclosed area is increasing at the rate of

85130 The volume of a spherical ball is increasing at a rate of \(4 \pi \mathrm{cm}^{3} \mathrm{~s}^{-1}\). The rate at which its radius increases when its volume is \(288 \pi \mathrm{cm}^{3}\) is cm. \(\mathrm{s}^{-1}\)

85131 The diameter and altitude of a right circular cone, at a certain instant, were found to be 10 \(\mathrm{cm}\) and \(20 \mathrm{~cm}\) respectively. If its diameter is increasing at a rate of \(2 \mathrm{~cm} / \mathrm{s}\), then at what rate must its altitude change in order to keep its volume constant?
