# Area of a Regular Polygon Calculator

Regular polygon is the actually the one which possesses the same size of its vertex angle as its edges with same length. All the regular polygons are associated with two perticular circles.

The first circle is known as the circumcircle, circle drawn close to the exterior of the polygon in order to touch all corners (or vertices). This circle is generally essential when creating a polygon.
The second circle is known as the incircle this is the circle driven within the polygon in order to touch all edges. Its dimension is given here from the IN radius.
Within this diagram, the CIRCUM circle is actually RED; the INcircle will be BLUE.
In the event the perimeter is required, the formula is number of edges x length of one edge

 Show values to . . . 3 4 5 6 7 8 9 significant figures.
 number of edges(3 to 1000) length of edge units area square units in-radius units circum-radius units

Note: Appropriate units have to be attached. Very small and Large numbers show up in e-Format. Unvalued zeros on all the numbers are already suppressed.

Polygons are known as by the amount of edges they've. Probably the most widely used names are:

 Edges Name 3 triangle 4 quadrilateral 5 pentagon 6 hexagon 7 heptagon 8 octagon 9 nonagon 10 decagon 11 undecagon 12 dodecagon

## Formula for Area of a Regular Polygon

The Formula for area of regular Polygon is:

 n = number of sides s = length of a side r = apothem (radius of inscribed circle) R = radius of circumcircle
