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
