To calculate the surface area of a cylinder: Work out the area of the two circular faces (2 × π\(r\)²). Work out the curved surface area, this is the rectangular face (2π\(r\) × \(h\)).

Is it possible that space-time is curved in such a way that ... star is going along the length of the cylinder, all it can ever do is go out, because the surface is flat in that direction; there ...

Explanation: Since the total surface area of cylinder of radius r and height h = 2πrh + 2πr 2. When one cylinder is placed over the other cylinder of same height and radius, Curved Surface area ...

Figure 1: Colloidal crystals on curved oil–glycerol interfaces ... requires half the topological charge of a sphere, whereas a cylinder can be defect-free with a requirement of 0 total charge.
