This **Volume of a Nonagon** calculator computes the volume a column with a regular nonagon base and top.

**INSTRUCTIONS:** Choose units and enter the following:

- (
**s**) Length of Sides of Nonagon - (
**h**) Height of Nonagon Column

**Nonagon Volume (V):** The volume is returned in cubic meters. The total surface area (SA) of the column and the area of the top (A) are returned in square meters However, these can be automatically converted to compatible units via the pull-down menu.

A regular nonagon has nine equal sides and equal angles. The formula for the volume of a Nonagon is:

V = 9/4•cot(π/9)•s^{2}•h

where:

- V = volume of the nonagon column
- s = length of the sides of the nonagon
- h = height of the column

**Volume **is a three dimensional measurement of the amount of space taken up by an object. Volume units are cubic measurements for solid objects such as cubic inches and cubic meters. Fluids have separate volume units such as liters, fluid ounces, cups, gallons, and barrel.

The volume of an object can measured by the liquid it displaces or be calculated by measuring its dimensions and applying those dimensions to a formula describing its shape. Many such calculations are available in the following list of calculators.

In many cases, the calculators are for a column with a geometric shaped base and vertical sides. One basic formula for volume is area times a Height when the volume has vertical sides.
