A water tank has a shape of an inverted right circular cone with its axis vertical and vertex lower-most. Its semi-vertical angle is `tan^(-1)((3)/(4))` . Water is poured into it at a constant rate of `3` cubic meter per hour. The rate at which the level of the water is rising at an instant when the depth of water in the tank is `4m` is

A water tank has the shape of an inverted right - circular cone with its axis vertical and vertex lower most. Its semi - vertical angle is tan^(-1)((1)/(2)) . Water is poured into it at a constant rate of 5 cubic meter per minute. Find the rate at which the level of the water is rising at the instant when the depth of water in the tank is 10 m.

A water tank has the shape of an inverted righ circular cone with its axis vertical and vertex lowermost . Its semi-vertical angle is tan^(-1)(0.5) . Water is poured into it at a constant rate of 4 cubic meter per hour . Find the rate at which the level of the water is rising at the instant when the depth of water in the tank is 2 m.

A water tank has the shape of an inverted right circular cone with its axis vertical and vertex lowermost.Its semi-vertical angle is tan ^(-1)(0.5). Water is poured into it at a constant rate of 5cubic metre per hour.Find the rate at which the level of the water is rising at which the level of the water is in the tank is 4m.

A water tank has the shape of an inverted right circular cone, whose semi-vertical angle is tan ^(-1)((1)/(2)) . Water is poured into it at a constant rate of 5 cu m/min. Then, the rate (in m/min) at which the level of water is rising at the instant when the depth of water in the tank is 10 m is

A water tank has the shape of a cube with each side of length 3 metre. Water is poured into it at a constant rate of 27 cubic metre per hour. Then,the rate at which the level of the water is rising at the instant, when the depth of water in the tank is x, (0 < x < 2), is (in metre per hour) (i)x (ii) 3x (iii) 9x (iv) 3

An inverted cone has a depth of 40 cm and a base of radius 5 cm. Water is poured into it at a rate of 1.5 cubic centimetres per minutes. Find the rate at which the level of water in the cone is rising when the depth is 4 cm

Whater is poured into an inverted cone of semi-vertical angle 45^(@) at rate of 2 cu. in . /min .The rate at which the depth of water in the cone is increasing when the depth is 4 in. is

The bottom of a rectangular swimming tank is 25 m by 40m. Water is pumped into the tank at the rate of 500 cubic metres per minute. Find the rate at which the level of water in the tank is rising.
