Let's look at the geometric characteristics of a cylinder. But first, please review the definition of Volume Of Three-Dimensional Shapes.

- A cylinder is a two dimensional circle with height; with height it becomes a three dimensional shape.
- The trick to determining the volume of a cylinder is to compute
the Circle area
**B**ase: Circle Area. Once you compute the Circle area and multiply it by the Cylinder height. You now have the volume of the cylinder. - Special note, the
**Base**and**Height**of a cylinder must be greater than zero.

**Volume Of A Cylinder Formula**

Formula = (Base area) × Height =

Formula = (π × r^{2}) × H
