1. What is the Width of Dodecagon?

The width of a dodecagon is the horizontal distance from the leftmost edge to the rightmost edge of the regular dodecagon. It's an important geometric measurement used in various mathematical and engineering applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ w = \frac{(2+\sqrt{3}) \times r_c}{\frac{\sqrt{6}+\sqrt{2}}{2}} \]

Where:

\( w \) — Width of Dodecagon (m)
\( r_c \) — Circumradius of Dodecagon (m)
\( \sqrt{3} \) — Square root of 3 (approximately 1.732)
\( \sqrt{6} \) — Square root of 6 (approximately 2.449)
\( \sqrt{2} \) — Square root of 2 (approximately 1.414)

Explanation: This formula calculates the width of a regular dodecagon based on its circumradius, using mathematical relationships between the geometric properties of the shape.

3. Importance of Width Calculation

Details: Calculating the width of a dodecagon is crucial in geometry, architecture, engineering design, and various mathematical applications where precise dimensional measurements are required.

4. Using the Calculator

Tips: Enter the circumradius value in meters. The value must be positive and greater than zero for accurate calculation.
