1. What is Diagonal of Hexadecagon across Three Sides?

The Diagonal across Three Sides of a Hexadecagon is the straight line joining two non-adjacent vertices across three sides of the 16-sided polygon. It represents one of the various diagonal measurements possible in a regular hexadecagon.

2. How Does the Calculator Work?

The calculator uses the mathematical formula:

\[ d3 = d8 \times \sin\left(\frac{3\pi}{16}\right) \]

Where:

\( d3 \) — Diagonal across Three Sides of Hexadecagon (meters)
\( d8 \) — Diagonal across Eight Sides of Hexadecagon (meters)
\( \pi \) — Archimedes' constant (approximately 3.14159)
\( \sin \) — Sine trigonometric function

Explanation: This formula calculates the diagonal across three sides based on the known diagonal across eight sides using trigonometric relationships specific to a regular hexadecagon.

3. Importance of This Calculation

Details: Calculating diagonals in regular polygons is essential in geometry, architecture, and engineering design. Understanding these relationships helps in precise measurements and constructions involving polygonal shapes.

4. Using the Calculator

Tips: Enter the diagonal across eight sides measurement in meters. The value must be positive and valid. The calculator will compute the corresponding diagonal across three sides using the trigonometric formula.
