1. What is the Area of Nonagon Formula?

The formula calculates the area of a nonagon (9-sided polygon) when the diagonal across two sides is known. It uses trigonometric functions to determine the area based on the given diagonal measurement.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( A \) — Area of Nonagon (m²)
• \( d2 \) — Diagonal across Two Sides of Nonagon (m)
• \( \pi \) — Mathematical constant pi (approximately 3.14159)
• \( \sin \) — Trigonometric sine function

Explanation: The formula derives from the geometric properties of a regular nonagon, using the sine function to calculate the area based on the diagonal measurement across two sides.

3. Importance of Area Calculation

Details: Calculating the area of a nonagon is important in geometry, architecture, and various engineering applications where nonagonal shapes are used.

4. Using the Calculator

Tips: Enter the diagonal across two sides of the nonagon in meters. The value must be positive and greater than zero.
