1. What is Circumradius of Octagon?

The Circumradius of Octagon is the radius of the circumcircle of a Regular Octagon, which is the circle that contains all vertices of the octagon. It represents the distance from the center of the octagon to any of its vertices.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \(\sqrt{1 - \frac{1}{\sqrt{2}}}\) — Mathematical constant derived from octagon geometry
• Medium Diagonal of Octagon — The length of medium diagonals of the octagon

3. Formula Explanation

Details: This formula establishes the relationship between the circumradius and the medium diagonal of a regular octagon. The constant \(\sqrt{1 - \frac{1}{\sqrt{2}}}\) is derived from the geometric properties of a regular octagon and represents the ratio between these two measurements.

4. Using the Calculator

Tips: Enter the medium diagonal length of the octagon in meters. The value must be positive and greater than zero. The calculator will compute the corresponding circumradius.

5. Frequently Asked Questions (FAQ)

Q1: What is a regular octagon?
A: A regular octagon is an eight-sided polygon where all sides are equal in length and all interior angles are equal (135 degrees each).

Q2: What is the medium diagonal of an octagon?
A: The medium diagonal is the line joining one vertex and any one of the vertices that are closest to the opposite vertex of the first vertex in a regular octagon.

Q3: How accurate is this formula?
A: This formula is mathematically exact for regular octagons and provides precise results when correct measurements are input.

Q4: Can this calculator be used for irregular octagons?
A: No, this calculator is specifically designed for regular octagons where all sides and angles are equal.

Q5: What are the practical applications of calculating circumradius?
A: Calculating circumradius is important in various fields including architecture, engineering, and design where octagonal shapes are used, particularly in structural design and spatial planning.
