Question 729534: Please let know if I solved this problem correctly. 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.
S= 2*(pi)*rh+2*(pi)*r^2
S= {2*(pi)*0.9*(2.6)}+(2*(pi)*0.9^2)
S= (2*(pi)*2.34)+(2*(pi)*0.81)
S= 4.68*(pi)+1.62*(pi)
S= 14.6952+5.0868
S= 19.782
S= 19.8 ft^2
