Derivation of the Annulus Formula

The annulus formula is derived from the formula for the area of a circle, A = πr², and the formula for the volume of a cylinder, V = πr²h. By subtracting the area of the inner circle from the area of the outer circle, we get the area of the annulus, which is then multiplied by the height to get the volume.

1. The area of the outer circle is calculated by squaring the outer radius and multiplying by pi.
2. The area of the inner circle is calculated by squaring the inner radius and multiplying by pi.
