Mammoth Memory

Three dimensions


3D shapes with a point means the area will be a third

Area of base = `\pir^2` 

Volume of cone = `1/3\times\volume\ of\  a\  cyli\nder` 

Volume of cone = `1/3\times \Area\ of\  base\times\ height` 

Volume of cone = `1/3\times \pir^2\times\ height` 

3 cones make a cylinder if you add them up

3 cones fill 1 cylinder (with the same size base and height).



Areas shaded blue are all equal.
