Please help me with the model of this using skewer stick and cardboard, please record step by step progress of how you complete the solid. Thanks

Extracted text: Reflect your function in the x-axis and add it to your graph in the chosen domain. Sketch the outline of the solid created when the function revolves around the x-axis. We could model this solid using a series of discs (commonly known as the slicing method). Each disk will have radius of the corresponding function value. Using thick cardboard and skewer sticks, make a 3-D model of the solid of revolution with a minimum of 6 discs. Example below using 4 disks: f(r) = 4, 1
