If I did not solve the problem correctly, will you please provide me with the correct formula to solve the problem. The inside of a cylindrical steel drum, including the top and bottom, is to be painted with rust-inhibiting paint. The inside diameter of the drum is 1.8 feet, and the height is 2.6 feet. What is the total surface area to be painted? Use 3.14 for pi.
