Consider a spherical water tank with radiuS 3 feet. A circular hole with radius 0.7 inches is cut into the bottom of the tank. Initially, the water level in the tank is 2 feet. Determine A(y), the horizontal cross-sectional area of the tank at height y. Then, use Torricelli's Law to determine the time tempty when the tank is empty. (Use 32 ft/s? a he gravitational constant.) 4(y) еmpty seconds
