Definitions [1]
Definition: Cylinder
A cylinder is a three-dimensional solid figure that has two identical circular bases joined by a curved surface at a particular distance from its centre, which is its height.
Formulae [2]
Volume of a cuboid = l x b x h
volume of the cube = l x l x l = l3
Formula: Cylinder
Curved surface area of a cylinder = circumference of base × height
= 2πrh
Total surface area = Curved surface area + 2 (Area of cross-section)
= 2πrh + 2πr2
= 2πr(r + h)
Volume = Area of cross-section × height (or, length)
= πr2h
