Volume of cylinder
Volume of A Cylinder: Volume of Cylinder = Measure of the space occupied by the cylinder
= The area of each circular sheet x Height
=
Thus, Volume of a right circular cylinder = Area of the base x Height =
Illustration: Find the volume of a right circular cylinder, if the radius of its base and height are 7 cm and 15 cm respectively.
Solution: We know that, Volume of cylinder = . Here, r = 7cm and h = 15cm

Illustration: A lead pencil consists of a cylinder of wood with a solid cylinder of graphite filled into it. The diameter of the pencil is 7mm, the diameter of the graphite is 1 mm and the length of the pencil is 14 cm. Find the:
(i) Volume of the graphite
(ii) Volume of the wood
(iii) The weight of the whole pencil, if the specific gravity of the wood is and that of the graphite is
.
Solution: We have,
Diameter of the graphite cylinder = 1 mm =
So, radius of the graphite cylinder
Length of the graphite cylinder = 14 cm
Volume of the graphite cylinder
(ii) We have,
Diameter of the pencil = 7 mm
So, radius of pencil
Length of pencil = 14 cm
Volume of the pencil
