The surface area of a cylinder is given by A = 2πrh + 2πr^2. You're given the radius, r = x+2, and the height, h = x + 5. Plug them in and you're done.
Pythagorean Theorem:
500^2 = 300^2 + x^2
250,000 = 90,000 + x^2
160,000 = x^2
x = +/- 400 use the positive root
height is 400ft
The answer is C most likey
