Solve the problem.Imagine a large tank with cross-sectional area A. The bottom of the tank has a circular drain with cross-sectional area a. Assume the tank is initially filled with water to a height h(0) = H. The height of the water as it flows out of the tank is described by the equation 
where 
and 
is the acceleration due to
gravity. Find the water height function for 
Then determine the approximate time at which the tank is first empty. If necessary, round to two decimal places.
