Year 8 Maths activity to calculate the volume of cylinders using photographs of containers and tanks on the farm.

1. Year 8 Maths: Measurement and Space Learning Intention: “To understand the measurements required and how to calculate the volume of a cylinder.”

2. 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

3. 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.
