Oops, it looks like there was a mistake in my previous response. Let's recalculate the surface area of the cylinder. The formula is 2πr^2 + 2πrh. The radius is 15 inches, so the surface area is 2 * 3.14 * 15^2 + 2 * 3.14 * 15 * 15. Let's solve it together!
2 * 3.14 * 15^2 + 2 * 3.14 * 15 * 15
= 2 * 3.14 * 225 + 2 * 3.14 * 225
= 1413 + 943.5
= 2356.5
So, the correct surface area of the cylinder is 2356.5 square inches. Thank you for bringing that to my attention!
