The surface area of a right circular cylinder can be calculated using the formula:
Surface Area = 2πrh + πr^2
Given that the surface area is 522.81 square feet, the radius is 9 feet, and using 3.14 for π, we can plug these values into the formula and solve for the height (h).
522.81 = 2(3.14)(9)h + (3.14)(9)^2
522.81 = 56.52h + 254.34
522.81 - 254.34 = 56.52h
268.47 = 56.52h
h = 268.47 / 56.52
h = 4.75 feet
Therefore, the height of the curved surface of the right circular cylinder is approximately 4.75 feet.
