The Area of a Pentadecagon calculator computes the area of a regular polygon with 15 equal sides and equal angles of 156°.
INSTRUCTIONS: Choose units and enter the following:
- (s) - Length of Side
Total Area: The area (A) is returned in square meters. However, this can be automatically converted to other area units via the pull-down menu.
The Math / Science
The formula for the area of a pentedecagon is:
A = 15/4 * s2 cot(π/15)
where:
- A = area of the pentedecagon
- s = length of a side
For other area calculators see:
- Area of Circle - Circle approximates a polygon as the number of sides approaches infinity.
- Area of Triangle - Three Sides
- Area of Quadrilateral - Four Sides
- Area of Pentagon - Five Sides
- Area of Hexagon - Six Sides
- Area of Heptagon - Seven Sides
- Area of Octagon - Eight Sides
- Area of Nonagon - Nine Sides
- Area of Decagon - Ten Sides
- Area of Hendecagon - Eleven Sides
- Area of Dodecagon - Twelve Sides
- Area of Polygon - Any number of sides (n).
