The formula for the surface area of a cylinder is:

Plug in what we know, use 3.14 to approximate for pi(radius is half the diameter, 30/2 = 15):

Simplify:

Subtract 1413 to both sides:

Divide 94.2 to both sides:

So the height is approximately 45 millimeters.
The rule that describes this translation is

Answer:
The number is 8.
Step-by-step explanation:
If the positive number is x then:
x^2 = 5x + 24
x^2 - 5x - 24 = 0
(x - 8)(x + 3) = 0
x =8, -3 .
x is positive so the answer is 8.
