A chemical company is designing a cylindrical storage tank with a fixed volume, $V$. The cost of the material used for the tank’s construction depends on its surface area. The tank has a circular base and top, and the curved side is made from a different material. Let $r$ be the radius of the circular base/top and $h$ be the height of the tank. The base and top cost $a$ dollars per unit area, while the curved side costs $b$ dollars per unit area.
a. Express the total cost, $C$, of the tank as a function of $r$, $V$, $a$ and $b$.
