T=(R^(2))/(r^(2))sqrt((2h)/(g)) Suppose an open cylindrical tank has a round drain with radius t in the bottom of the tank. When the tank is filled with water to a depth of h centimeters, the time it takes for all the water to drain from the tank is given by the formula above, where R is the radius of the tank (in centimeters) and g=980"cm/"s^(2) is the acceleration due to gravity. Suppose such a tank has a radius of 2 meters and is filled to a depth of 4 meters. About how many minutes does it take to empty the tank if the drain has a radius of 5 centimeters? (1 meter=100 centimeter).
