The Area of Polygon from Number of Sides and Inner Radius calculator computes the area of a regular polygon of n sides circumscribed around a circle of radius r.
INSTRUCTIONS: Choose units and enter the following:
Polygon Segment Area (A): The calculator returns the area in square meters. However, this can be automatically converted to compatible units via the pull-down menu.
The formula for the area of a regular polygon based on the number of sides and the inner radius is:
`A = n * r^2*tan(pi/n)`
