A cylinder of radius r and height h (of the cylindrical part) with two hemispherical caps of radius r on the ends.

What are the formulas?

Volume = πr²h + (4/3)πr³. Surface = 2πr(h + 2r). Total height = h + 2r.

Use the same unit for r and h; volume will be in cubic units, surface in square units.
