Final answer:
To solve for the height h in the cylinder's surface area formula, subtract 27m^2 from the total surface area S, and then divide by the product of 2, a (pi), and r (radius).
Step-by-step explanation:
The question asks to solve for the variable h (height) in the surface area formula of a cylinder. The given surface area, S, is 27m^2 plus twice the product of pi (represented as a), radius (r), and height (h). To isolate h, we can rearrange the formula. The correct rearrangement to solve for h is obtained by subtracting 27m^2 from S, then dividing by the product of 2, a (which stands for pi), and r. The correct formula is h = (S - 27m^2) / (2ar).
