Regular hexagon abcdef is inscribed in a circle with a radius of 2 units.
find measure of central angle agf
apothem a=gh
side length s=
perimeter p=
hexagon area a=

For the triangle with side lengths equal to the radius of the circle is a equilateral.
so all the angles are 60 degrees

side lengths are the same as the radius as shown in the diagram.
so s = 2units

p = 2 x #ofSides
   = 2 x 8 = 16

area of a hexagon formula proof and formula itslef is sligtly complicated.
Instead we can find the area of 1 triangle, and then multiply it by 6, since a hexagon is made up of these 6 triangles

area of triangle = 2x2 /2 = 2

2 x 6  = 12units^2

Ibelieve the answer would be 7, 13, 23
