As shown in the figure, the area of the regular polygon inside the circle with the radius R can be obtained as follows.

¢¹ ¥è = 360/n
¢¹ The area of a triangle At=(1/2)*R*R*sin(¥è)

Therefore, the area A of the n regular polygon is as follows.

A = (1/2)*n*R^(2)*sin(360/n)

If you know the area A, the radius R is

R = (2*A / (n*sin(360/n)))^(1/2)

*** Âü°í¹®Çå[References] ***

R = (2*A / (n*sin(360/n)))^(1/2)
