Hexagon Calculator
Compute area, perimeter, apothem and interior angle of a regular hexagon.
Inputs
units
Area
93.5307sq units
Perimeter
36.0000units
Apothem
5.1962units
Interior Angle
120.00°
Step by step
Interior angle
(6−2)×180/6
= 120°
Apothem
a = 6 / (2 × tan(π/6))
= 5.1962
Area
A = ½ × 36 × 5.1962
= 93.5307
How it works
A regular hexagon has 6 equal sides. Each interior angle is 120°. The area formula is ½ × perimeter × apothem, or equivalently (3√3/2)s².
Formulas
Area
A = (3√3/2) × s²
- s
- Side length
Apothem
a = s × √3/2
- s
- Side length
Frequently Asked Questions
Why are hexagons common in nature?
Hexagons tile a plane with no gaps and minimize perimeter for a given area (honeycombs, basalt columns).
What is the relationship between apothem and side for a hexagon?
The apothem equals (s√3)/2, and the circumradius equals the side length.
