## What is an octagon?

Octagon is a polygon with eight sides and eight vertices. An octagon, like any other polygon, can be either convex or concave, as illustrated in the next figure. A convex octagon has none of its interior angles greater than 180°. To the contrary, a concave octagon (or polygon) has one or more of its interior angles greater than 180°

## How to Calculate Circumradius of Octagon?

Circumradius of Octagon calculator uses circumradius = (Side/2)*sqrt(4+2*sqrt(2)) to calculate the Circumradius, The Circumradius of octagon formula is defined as straight line from the centre to the circumference of an octagon, where radius= radius of octagon Rc=1.307*a where a is side and Rc is circumradius of octagon. Circumradius and is denoted by rc symbol.

How to calculate Circumradius of Octagon using this online calculator? To use this online calculator for Circumradius of Octagon, enter Side (S) and hit the calculate button. Here is how the Circumradius of Octagon calculation can be explained with given input values -> 11.75907 = (9/2)*sqrt(4+2*sqrt(2)).

### FAQ

The Circumradius of octagon formula is defined as straight line from the centre to the circumference of an octagon, where radius= radius of octagon Rc=1.307*a where a is side and Rc is circumradius of octagon and is represented as rc = (S/2)*sqrt(4+2*sqrt(2)) or circumradius = (Side/2)*sqrt(4+2*sqrt(2)). The side 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.
How to calculate Circumradius of Octagon?
The Circumradius of octagon formula is defined as straight line from the centre to the circumference of an octagon, where radius= radius of octagon Rc=1.307*a where a is side and Rc is circumradius of octagon is calculated using circumradius = (Side/2)*sqrt(4+2*sqrt(2)). To calculate Circumradius of Octagon, you need Side (S). With our tool, you need to enter the respective value for Side and hit the calculate button.
