A conical water tank with vertex down of 12 meters height has a radius of 5 meters at the top. If water flows into the tank at a rate 10 cubic m/min, how fast is the depth of the water increases when the water is 8 metres deep?

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

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 water tank has the shape of an invertd circular cone with base radius 2 metres and height 4 metres. If water is being pumped into the tank at the rate of 2m^(3)//mm . Find the rate at which the water level is rising when the water is 3m deep

A water tank is in the shape of a right circular cone with its axis vertical and vertex down. Its height and diameter are same. Water is powered into it at a constant rate of 2m^3//minute . Find the rate at which water level is increasing when depth of water in the tank is 6m.

A rectạngular water tank has inner dimensions 5 metres, 4 meters and 2 meters. How many litres of water it contain?

Half of a cuboidal water tank with length of 2· 1 m and breadth of 1·5 m is filled with water. If 630 litres water is poured more into the tank, then calculate the depth of water that will be increased by.

Water is flowing into a right circular conical vessel, 45 cm deep and 27 cm in diameter at the rate of 11 cm^(3) /min. How fast is the water-level rising when the water is 30 cm deep?
