What is a polygon..?

In geometry, a polygon can be defined as a flat or plane, two-dimensional closed shapes with straight sides. It does not have curved sides. Polygons can be of two types: Regular Polygons – Polygons that have equal sides and angles are regular polygons. Irregular Polygons – Polygons with unequal sides and angles are irregular polygons.

How to Calculate Radius of the circumscribed circle of a regular polygon?

FAQ

What is Radius of the circumscribed circle of a regular polygon?
The Radius of the circumscribed circle of a regular polygon formula is defined as the radius of the circle circumscribing the regular polygon and is represented as r=(a)/(2*(sin((180*pi/180)/n))) or Radius=(Side A)/(2*(sin((180*pi/180)/Number of sides))). Side A is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back and The number of Sides is used to classify the polygons.
How to calculate Radius of the circumscribed circle of a regular polygon?
