Regular Polygon Cicumcircle Formula - Areas

Formula:

Circumradius (r) = l / (2 x sin( π / n ))
Area of the polygon = ( n x l2 ) / ( 4 x tan( π / n ) )
Regular Polygon Circumcircle Area = 3.14 x r2



Where,

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