Simple online calculator to calculate the length of the sides, areas of circle and a regular polygon.
Code to add this calci to your website
Just copy and paste the below code to your webpage where you want to display this calculator.
Formula Used:
Length of the side of the polygon = 2 * r * sin ( PI / n )
Area of the polygon = 0.5 * n * r2 * sin ( 2PI / n )
Area of the Circle = PI * r2
Where,
n = Number of sides of the polygon,
r = Circumradius of the polygon
