    Design an algorithm that helps students calculate the lateral surface area of their cylindrical learning module display, using only the height and radius measurements they collect in class. The lateral surface area calculation will help students understand how much decorative paper they need to cover the curved surface of their display, excluding the top and bottom circular faces.
