    Design an algorithm for the adaptive learning platform that calculates the lateral surface area of a cylindrical object, helping students master geometric concepts through practice. The algorithm should take the radius of the cylinder's base and its height as inputs, with the platform using the accuracy of students' calculations to adjust subsequent problem difficulty. The lateral surface area calculation will focus specifically on the curved surface area (excluding the circular bases) to help students understand the relationship between circular measurements and rectangular area.
