Volume and Surface Area of Cylinder

Volume and Surface Area of Cylinder

Secondary 1

A right circular cylinder has two congruent circular bases in parallel planes, with the line joining their centres perpendicular to the bases. Its curved surface joins the two circular boundaries. A cylinder is not a polygonal prism, but it has the same volume rule: \(V=Ah=\pi r^2h\), where \(h\) is the perpendicular height and \(r\) is the radius.
