Definition of a cylinderA cylinder is a threedimensional solid that contains two parallel bases connected by a curved surface.A cylinder has two parallel circular bases and a curved surface. A cylinder has a lateral surface and two bases. The bases are parallel and identical. They are generally circular. A cylinder has three faces : two circular and a rectangular one. It is a round object with two circles on each end that have the same size. The cylinder of revolution is the surface generated by the revolution of a line parallel to an axis, around this axis. A right circular cylinder can also be thought of as the solid of revolution generated by rotating a rectangle about one of its sides. A cylinder is a solid object with :  two identical flat ends that are circular or elliptical  one curved side A cylinder has the same crosssection from one end to the other. To go furtherThe bases are always congruent and parallel to each other.The radius r of a cylinder is the radius of a base. The height h is the perpendicular distance between the bases. A cylinder is a right circular prism. Furthermore a cylinder is a solid object with two identical flat circular ends and a curved rectangular side. Finally, like other prisms, the volume of a cylinder can be obtained by multiplying height by base area. π (pi) is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle's size, this ratio will always equal π (pi). In addition, the value of π (pi) is approximately 3.14 in decimal form. Volume of a cylinder formulaThe volume of a cylinder is equal to the product of the area of the circular base and the height of the cylinder.The formula for the volume of a cylinder is V = π x r² x h, with r = radius and h = height of the cylinder. Volume is the amount of space a 3dimensional figure occupies.
