Find the radius of the circle with . A hexagon can be divided into 6 equilateral triangles with sides of length 18 and angles of 60° The trig area rule can be used because 2 sides and the included angle are known: Area hexagon = 6 × 1 2(18)(18)sin60° × × × ×x = 63 × 1 2 324162 × √3 2 In geometry, the circumscribed circle or circumcircle of a polygon is a circle which passes through all the vertices of the polygon. a. the hexagon is circumscribed about the circle. Call that a. This is the largest hexagon that will fit in the circle, with each vertex touching the circle. Favorite Answer. d. An elite few can both circumscribe a circle and be inscribed in a circle. By joining opposite sides of hexagon, it forms 6 central angles at centre O each of which = 360/6 = 60°. Find the area of the hexagon to the nearest tenth. c. the circle is congruent to the hexagon. In this paper we analyze and prove two properties of a hexagon circumscribed to a circle: Set a compass to the spread between C and F, and, with C … For each triangle, you can compute the area using either 1) Heron's formula, Area = √s(s− a)(s − b)(s −c), where s = 3 2 is half the perimeter of the triangle, and a, b, c are the length of the sides of the triangles (all 1 in this case). The circle is inscribed in the polygon and the polygon is circumscribed about the circle. Patty found a battery-powered toy car in her basement that moved at a speed of 23 mm per second. And actually, I'm going to go beyond the diameter of the circle. Set a compass to the spread between E and C, and, with E as a center, strike the arc CF. The common length of the sides equals the radius of the circumscribed circle or circumcircle, which equals times the apothem (radius of the inscribed circle). REGULAR HEXAGON IN A GIVEN CIRCUMSCRIBED CIRCLE. Realize that a hexagon is six equilateral triangles stacked together. A regular hexagon is circumscribed by a circle of radius 6cm.
