Surface Area Calculator

The surface area of a closed cylinder can be calculated by summing the total areas of its base and lateral surface: base SA = 2πr 2. lateral SA = 2πrh. total SA = 2πr (r + h) where r is radius and h is height. Jeremy has a large cylindrical fish tank that he bathes in because he doesn't like showers or bath tubs.

Rolling processes - Al-Mustansiriya University

In flat rolling, the work is squeezed between two rolls so that its thickness is reduced by an amount called the draft: =2R (1-cosα) 5.1 Where d = draft, mm (in); = starting thickness, mm (in); and = final thickness, mm (in).R = roll radius in mm and (α) = bite angle in degree.
