# Regular Polygon Calculator

Posted by Dinesh onThis calculator calculates the **length of the side of the polygon, area of the polygon, area of the circle, area ratio** using enter the number of sides of the polygon(minimum 3), enter the circumradius values.

## Regular Polygon Calculation

### Formula:

Length of the side of the polygon = 2 * r * sin ( PI / n )

Area of the polygon = 0.5 * n * r^{2} * sin ( 2PI / n )

Area of the Circle = PI * r^{2}

n = Number of sides of the polygon,

r = Circumradius of the polygon
