Many objects 
that you see in your day to day life like Book, Pencil box, Ice cream 
cone, Football and Cylinder are three dimensional objects. All these 
objects occupy some shape and have three dimensions –length, 
breadth and height or depth.
 In Geometry , the shape or the figure that has 
three(even higher) dimensions, are known as solids or three 
dimensional shapes. The study of the properties , volume and the 
surface area of three dimensional shapes is called solid Geometry

 They have length , width and height.

the lines which are parallel to a given line and which pass through a 
fixed plane curve in a plane not parallel to the given line. Such 
Cylinders have , at times, been referred to as generalized cylinders.
Cylinders are solid with circles at both ends and a smoothly curving 
surface all around.
     In differential geometry, a cylinder is defined more broadly as any 
ruled surface which is spanned by a one-parameter family of 
parallel lines. A cylinder whose cross section is an ellipse, parabola 
or hyperbola is called an elliptic cylinder, parabolic cylinder, or 
hyperbolic cylinder respectively.
 
        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.

2) The base is the same as the top
3) From base to top the shape stays the same
4) It has one curved side
5) It is not a polyhedron as it has a curved surface

 When the two ends are directly aligned on each other , it is 
a RIGHT CYLINDER otherwise it is an OBLIQUE CYLINDER

enclosed by a closed surface or the amount of space occupied 
by an object. Volume is measured in cubic mm , cubic cm,
cubic m or cubic km.
 Volume = Length x Width x Height
    
HOW TO FIND THE VOLUME OF A CYLINDER

      To calculate the volume of a cylinder we 
need the radius or diameter of the circular base or top and the 
height of a cylinder .
        The volume of a cylinder is equal to the product of the area of 
the circular base and the height of the cylinder.
 Calculation of the volume of a cylinder is useful when 
designing cylindrical object such as :
 Culverts 
 Cylindrical water tanks or wells
 Perfume or Chemical bottles
 Cylindrical containers and pipes
 Cylindrical flasks use in Chemistry lab

 The formula for the volume of a cylinder is given as:
Volume of a cylinder = πr2h
  cubic units 
Where 
 πr2 = Area of a circle;
  π  = 3.14 
 r = radius of the circular base and
   h = height of a cylinder.

height 7cm.
Solution;
 Volume of a cylinder  =πr2h
                      = 22/7x2x2x7
                      = 88cubic cm.
