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.
Without additional information, we have to assume that one sequence can begin immediately after another, and that each takes the same amount of time. The total time for 7 sequences is 7 times the time for one sequence.
