Water is running into a conical vessel, 15cm deep and 5cm in radius, at the rate of 0.1 `c m^3//s e c` . When the water is 6cm deep, find at what rate is the water level rising? the water-surface area increasing? the wetted surface of the vessel increasing?

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

Water is filowing into right circular conical vessel, 10 inch deep and 10 inch in diameter at the rate of 4 (inch) ""^(3) /min, How fast is the water-level rising when the water is 8 inch deep?

The surface area of a spherical bubble is increasing at the rate of 2 c m^2//s . When the radius of the bubble is 6cm, at what rate is the volume of the bubble increasing?

The surface area of a spherical bubble is increasing at the rate of 2 c m^2//s . When the radius of the bubble is 6cm, at what rate is the volume of the bubble increasing?

Water runs into an inverted conical tent at the rate of 20 ft^3 / min and leaks out at the rate of 5 ft^3 /min .The height of the water is three times the radius of the water's surface. The radius of the water surface is increasing when the radius is 5 ft, is
