Regular Polygon Circumcircle Area Calculator


Calculates the Circumradius, Area of the polygon, Area of the circumcircle and Ratio of the area for given values.

Enter the number of sides of the polygon (minimum 3)
Enter the length of side of the polygon

Circumradius
Area of the circumcircle
Area of the polygon
Ratio of the area

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 and

l = Length of the side of the polygon

Area of the polygon
