A water tank has the shape of an inverted circular cone with base radius 2m and height 4m. If water is being pumped into the tank, and at certain time t 0, the volume of the water V is given by V = 1/3r^2h, where r is the radius of the surface and h is the height of the water at a specific time during the pumping process. Find the expression V(h).
