    Design a function for an automated grading system that calculates the lateral surface area of cylindrical objects in student geometry submissions, where students provide measurements for radius and height. The system must accurately evaluate student answers by computing the area of the rectangular surface that would be formed if the cylinder were "unrolled," excluding the circular bases.
