Hexagon is a six sided polygon containing six interior angles each equal to 120o and their sum is 720o. All sides of the regular hexagon are equal. The perimeter of hexagon is the lengths of all its sides. Area is the total area of all 6 triangles contained int it. In circle radius is the radius of the largest circle that will fit in the polygon. The diagonal of hexagon is the length of line joining any two vertices.
Perimeter P = 6 $\times$ a

Area A = $\frac{3 \sqrt{3}}{2}$ $\times$ a2

Incircle (ri) = $\frac{\sqrt{3}}{2}$ $\times$ a

Diagonal d = 2 $\times$ a

The Hexagon Calculator is a online tool to calculate the perimeter, Area, in circle radius and diagonal of an hexagon. For a given side of a hexagon this calculator will calculate all the parameters related to it.

## Hexagon Formula

Step 1 : Read the given problem and observe the given length a.

Step 2 : To find the perimeter(P), Area(A), incircle (ri) and Diagonal use the below formulas
Perimeter P = 6 a

Area A = $\frac{3 \sqrt{3}}{2}$ $\times$ a2

Incircle (ri) = $\frac{\sqrt{3}}{2}$ $\times$ a

Diagonal = 2 $\times$ a

Substitute the values in above formula and get the answer.
