  # Volumes of Cylinders

In this worksheet, students calculate the volume of cylinders given their diameter and height. This content is premium and exclusive to EdPlace subscribers. Key stage:  KS 2

Curriculum topic:   Maths and Numerical Reasoning

Curriculum subtopic:   Volume and Capacity

Difficulty level:   #### 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 with radius r = πr2

We can write this instead of A, so the volume of a cylinder with radius r and height h = πr2h

Example

Find the volume of this cylinder in cm3 to 3 significant figures. Diameter = 6 cm

Radius = 6 ÷ 2 = 3 cm

Height = 12 cm

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