A cylindrical storage tank is to be painted only on its curved surface because the top and bottom will be covered later. To decide how much paint is required, which surface area should be used? (a) Total surface area of the cylinder\text{Total surface area of the cylinder} (b) Curved surface area plus one circular base\text{Curved surface area plus one circular base} (c) Only the curved surface area of the cylinder\text{Only the curved surface area of the cylinder} (d) 12 of the total surface area of the cylinder\dfrac{1}{2}\text{ of the total surface area of the cylinder}
