Three online calculators to calculate side, area, radius of inscribed circle and radius of circumscribed circle of regular polygons.
Let x be the side of a regular polygon, n the number of sides, r the radius of the inscribed circle and R the radius of the circumscribed circle.
Calculator 1
Given side x and number n, find r, R and the area A of the regular polygon.
Enter number of sides n and the length x of one side of the polygon and press "calculate". The outputs are: r radius of inscribed circle, R radius of circumscribed circle and the area A of the polygon.
Calculator 2
Given r radius of inscribed circle and number n of sides , find side x, radius R and the area A of the regular polygon.
Enter number of sides n and the inscribed radius r of the polygon and press "calculate". The outputs are: side x , radius R of circumscribed circle and the area A of the polygon.
Calculator 3
Given R radius of circumscribed circle and number n of sides , find side x, radius r and the area A of the regular polygon.
Enter number of sides n and the circumscribed radius R of the polygon and press "calculate". The outputs are: side x , radius r of inscribed circle and the area A of the polygon.
