To find the surface area of the cylinder with radius 11 inches (half of 22 inches) and height 12.5 inches, we can substitute these values into the formula:
SA = 2π(11)^2 + 2π(11)(12.5)
SA = 2π(121) + 2π(137.5)
SA = 242π + 275π
SA = 517π
SA ≈ 1624.05 square inches
Rounding to the nearest tenth, the surface area of the cylinder is approximately 1624.1 square inches.
