1. What is the Area of Hexadecagon Formula?

The area of a hexadecagon (16-sided polygon) can be calculated using the diagonal across six sides with the formula: \[ A = 4 \times \left( \frac{d_6 \times \sin(\pi/16)}{\sin(3\pi/8)} \right)^2 \times \cot(\pi/16) \] This formula provides an accurate measurement of the 2-dimensional space occupied by a regular hexadecagon.

2. How Does the Calculator Work?

The calculator uses the mathematical formula:

\[ A = 4 \times \left( \frac{d_6 \times \sin(\pi/16)}{\sin(3\pi/8)} \right)^2 \times \cot(\pi/16) \]

Where:

\( A \) — Area of Hexadecagon (m²)
\( d_6 \) — Diagonal across six sides (m)
\( \pi \) — Mathematical constant (approximately 3.14159)
\( \sin \) — Sine trigonometric function
\( \cot \) — Cotangent trigonometric function

Explanation: The formula calculates the area by relating the diagonal measurement to the geometric properties of a regular hexadecagon using trigonometric functions.

3. Importance of Area Calculation

Details: Calculating the area of geometric shapes is fundamental in mathematics, engineering, architecture, and various scientific fields. For complex polygons like hexadecagons, precise area calculations are essential for design, construction, and spatial analysis applications.
