Suppose the supercapacitor consists of a layered sandwich of the following materials: 2.5 um of insulation, 5 jm of copper foil, 5 qm of a dielectric material with dielectric constant k = 24700, 5um of copper foil, 2.5 um of insulation. The layers form a very long ribbon of width 0.9 m. They are then rolled up tightly into a cylindrical shape, where the height of the cylinder corresponds to the 0.9 m width of the ribbon. Determine the radius of the cylinder. Hence comment on the practicality of the supercapacitor proposal.
