Note on Units: Remember to keep them constant, and don't mix different units in the formulas!

Calculating the Volume of a Cylinder

Basic Formula

Volume = Pi * Radius² * Height

Basic Formula Worked Backwards for Height

Height = Volume / (Pi * Radius²)

Basic Formula Worked Backwards for Radius

Radius = SQRT(Volume / (Pi * Height))

Calculating the Surface Area of a Cylinder

Basic Formula

Surface Area = 2(Pi * Radius²) + (2 * Pi * Radius) * Height
