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 given side and angle?

Circumradius of octagon given side and angle calculator uses Radius=Side/(2*sin(Angle A/2)) to calculate the Radius, The Circumradius of octagon given side and angle formula is defined as Rc=a/2*sin(θ/2) where a is side and θ is central angle of octagon. Radius and is denoted by r symbol.

How to calculate Circumradius of octagon given side and angle using this online calculator? To use this online calculator for Circumradius of octagon given side and angle, enter Side (s) and Angle A (∠A) and hit the calculate button.
