## Volume of cylindersPresentation Transcript

• Year 8 Maths: Measurement and Space
Learning Intention: “To understand the measurements required and how to calculate the volume of a cylinder.”
• Volume of a Cylinder
The volume of any prism is equal to the area of the base multiplied by the height (or the distance between congruent faces).
The area of a circle is equal to A= Π r²
Π = approx. 3.14 or 22/7 and r = radius
So, the volume of a cylinder = Π r² x height
• Volume = Πr² x height
V = 3.14 x 1.5 x 1.5 x 2
V = 14.3m³
1m³ = 1000 litres
So the capacity of the tank is 14,300 litres.
