Area of the hexagon is given as 64.95cm^2 and the apothem is 4.33m. Now area of the circle inscribed is 3πa*a/4. Here we will see how to get the area of an n-sided regular polygon whose radius is given. If we want to find the area of the entire hexagon, we just have to multiply that by 6, because there are six of these triangles there. Central angle of hexagon = 60° forming isosceles triangle of 2 equal lengths 1 cm => area of isosceles triangle = (1/2)(1)(1)sin 60°. To solve this problem, we have drawn one perpendicular from the center to one side. by radius do you mean the distance from the centre to any vertex? Hexagon formula helps us to compute the location and boundary of hexagonal items. ... Each side of the triangle is the radius of the circle: 4. Calculations at a regular hexagon, a polygon with 6 vertices. this must be a regular hexagon, right? By joining opposite sides of hexagon, it forms 6 central angles at centre O each of which = 6 3 6 0 = 6 0 o . What is the approximate area of the decagon? 2.Find the area of a square with a radius of 12 inches.
