Q) CASE STUDY 06 A tank, as shown in the figure below, formed using a combination of cylinder and a cone, offers better drainage as compared to a flat-bottomed tank. A tap is connected to such a tank whose conical part is full of water. Water is dripping out from a tap at the bottom at the uniform rate of 2 〖𝐜𝐦〗^𝟑/𝐬. The semi-vertical angle of the conical tank is 45°. On the basis of given information, answer the following questions: (i) Find the volume of water in the tank in terms of its radius r. (ii) Find rate of change of radius at an instant when r = 2√𝟐 cm. (iii) (a) Find the rate at which the wet surface of the conical tank is decreasing at an instant when radius r = 2√𝟐 cm. (iii) (b) Find the rate of change of height ‘h’ at an instant when slant height is 4cm. (ii) Find the time at which the height of the ball is maximum
