Worksheet Overview

A cylinder can be considered as lots of circular discs stacked one above the other.



If the area of each circular disc is A and the height of the stack is h, then the volume = Ah.



Remember that the area of a circle is πr2 where r is the radius of the circle.


So the volume of a cylinder with radius r and height h = π x r2 x  h or as πr2




Find the volume of this cylinder in cm3 to 3 significant figures.


cylinder with diameter 6 cm and height 12 cm



Diameter = 6 cm

Radius = 6 ÷ 2 = 3 cm

Height = 12 cm


Volume = πr2h = π × 32 × 12 = π  x 9 x 12 = 339.29 ≈ 339 cm3 (3 s.f.)
