1. Geometry Volume of Cylinders

2. Volume  Volume – To calculate the volume of a prism, we first need to calculate the area of the BASE of the prism. This is then multiplied by the height of the prism to calculate the volume. l w h We find that: Volume = Area of Base x Height V = B x h

3. Volume  Volume – To calculate the volume of a cylinder, we use the same process. Calculate the area of the circular base (B).  A = π r 2 l B

4. Volume  We now know the area of B. To find the volume (V) we can multiply B by the height (h) of the cylinder. Combining the formulas…  V = B x h  V = π r 2 x h l B

5. Volume  So we know…the Volume of a Cylinder can be calculated,,, Volume of a Cylinder…  V = π r 2 x h l B

6. Volume  Calculate the Volume… B A 5cm 8cm

7. Volume  Calculate the Volume… A A 4.1m 1.9m
