A container is in the shape of an inverted cone. Its height is 6 m and radius is 4 m at the top. IF it is filled with water at the rate of `3m^3//min`, then the rate of change of height of water (in`m//min`) when the water level is 3 m is

A container is the shape of an inverted cone. Its height is 6m and radius is 4 m at the top. If it is filled with water at the rate 3m^(3)//min then the rate of change of height of water (in mt//min) when the water level is 3 m is

A container is in the shape of an inverted cone has height 8m and radius 6m at the top. If it is filled with water at the rate of 2m^(3) /minute, how fast is the height of water changing when the level is 4m?

A container in the shape of an inverted cone has height 12 cm and radius 6cm at the top. If it is filled with water at the rate of 12cm^(3)//sec , what is the rate of change in the rate of change in the height of water level when the tank is filled 8 cm?

An inverted cone with semi vertical angle 0=tan^(-1)((1)/(2)) is being filled with water at the rate of 5cm^(3) min.Then the rate of change of height of water when height of water is 10cm is

A tank is in the form of inverted cone, having height 8 meters and base radius 2 meters. Water is flowing into the tank at the rate of (1/8) m^3 /min. The rate at which the water level is rising, when the water is 2.5 meters deep is….. A) (8/ pi ) m/min B) (8/25 pi ) m/min C) (25 pi / 8) m/min D) (8/15 pi ) m/min
