\]Liam is designing a cylindrical water tank that must hold exactly 500 liters (equivalent to 0.5 m³) of water. If the material cost for the curved lateral surface is $40 per m² and the top and bottom each cost $55 per m² due to thicker reinforcement, what is the minimum cost to construct the tank, minimizing the surface area?
