Remember: The formula for surface area for cylinders are S= 2πrh + 2πr² The 2πr² represents the circular parts of the cylinder.
First, let's find the lateral side of the cylinder. → 2 (3.14)(6)(15) = 565.2 Next, find the circular parts. → 2 (3.14)(6²) → 2 (3.14)(36) = 226.08 Add the two answers together. →565.2 + 226.08 = 791.28 Round. Your final answer is 791.3 in² I hope this helps.
