Question:

Water is pumped at a uniform rate of 2 liters (1 liter = 1000 cubic centimeters) per minute into a tank shaped like a frustum of a right circular cone. The tank has altitude 80 centimeters and lower and upper radii of 20 and 40 centimeters, respectively (Figure 11). How fast is the water level rising when the depth of the water is 30 centimeters? Note The volume, V, of a frustum of a right circular cone of altitude it and lower and upper radii a and b is V = 1/3Ï€h ˆ™ (a2 + ab + b2).
