    Calculate the visible surface area that students can interact with on a cylindrical math manipulative tool, excluding its top and bottom faces, to help them understand geometric concepts through hands-on exploration. The manipulative's dimensions are defined by its radius (r) and height (h), where students must apply the formula for lateral surface area in a practical context.
