Find the area bounded by the arc square root x + square root y = 7, the x axis, and the line joining (16,9) and (9,16)

A farmer wants to repaint a thin, cylindrical water tank on their property. He only needs to paint the outer surface, not the top or the bottom of the cylinder. The tank has a height of 120 centimeters.and the base radius of the tank is 60 mm. Using linear approximations, estimate the volume of paint needed to add a layer 0.5mm thick to the curved outer surface.The volume of a cylinder can be calculated by V = pi(r^2)h
