Polygon Incircle Calculator

Posted by Dinesh on

This calculator calculates the inradius, area of the incircle, area of the polygon, ratio of the area using enter the number of sides of the polygon(minimum 3), enter the length of side of the polygon values.

Polygon Incircle Calculation


Inradius = l / 2 * tan(PI/n)
Area of the polygon = 0.5 * n * l * r
Area of the Incircle = PI * r2

n = Number of sides of the polygon,
r = Inradius,
l = Length of the side of the polygon
