All Features Of Cylinder Shape

Answer:
Cylinder
A cylinder is a closed solid that has two parallel (usually circular) bases connected by a curved surface.
Try this In the figure below, drag the orange dot to vary the dimensions of the cylinder.
Base and side-
A cylinder is a geometric solid that is very common in everyday life, such as a soup can. If you take it apart you find it has two ends, called bases, that are usually circular. The bases are always congruent and parallel to each other. If you were to 'unroll' the cylinder you would find the the side is actually a rectangle when flattened out. (See Surface area of a cylinder).
Height-
The height h is the perpendicular distance between the bases. It is important to use the perpendicular height (or 'altitude') when calculating the volume of an oblique cylinder.
Right and oblique cylinders-
When the two bases are exactly over each other and the axis is a right angles to the base, this is a called a 'right cylinder'. If one base is displaced sideways, the axis is not at right angles to the bases and the result is called an oblique cylinder. The bases, although not directly over each other, are still parallel.
In the applet at the top of the page, check the "allow oblique" box and drag the orange dot sideways to see an oblique cylinder.
