Web4 rows · The formula for the surface area of a half-cylinder can be given as, Total surface area ... WebSecond, the surface area of a cylinder is: $$ 2 \pi r^2 + 2 \pi r h \tag{1} $$ Now, we want to find the minimal surface area for a cylinder of a given volume. So the volume is a constant and we can the relation between the height as a function of the radius: $$ h(r) = …
