Volume

Volume = Π (r²) height

Volume of a Cylinder

Volume = Area of Base x Height

Base Shape = Circle

Area of Circle = Π x r²

Π = "Pi" >> rounded to 3.14

Open Ended

How will you be able to remember the difference between the Volume of

a Cylinder

( $$V=\pi\times radius^2\times height$$  ),

a CONE ( $$V=\frac{1}{3}\pi r^2h$$  ) and

a Sphere

( $$V=\frac{4}{3}\pi r^3$$ )
