1. What is Diagonal across Five Sides of Hendecagon?

A diagonal across five sides of a hendecagon is a straight line joining two non-adjacent vertices that spans five sides of the eleven-sided polygon. It represents one of the possible diagonal measurements in a regular hendecagon.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( d5 \) — Diagonal across five sides (m)
• \( S \) — Side length of the hendecagon (m)
• \( \pi \) — Mathematical constant pi (approximately 3.14159)
• \( \sin \) — Trigonometric sine function

Explanation: The formula uses trigonometric relationships in a regular hendecagon to calculate the diagonal length that spans five sides.

3. Importance of Diagonal Calculation

Details: Calculating diagonals in regular polygons is important for geometric analysis, architectural design, and understanding the spatial properties of polygonal shapes.

4. Using the Calculator

Tips: Enter the side length of the hendecagon in meters. The value must be positive and greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is a hendecagon?
A: A hendecagon is an eleven-sided polygon, also known as an undecagon.

Q2: How many diagonals does a hendecagon have?
A: A regular hendecagon has 44 diagonals in total, with different lengths depending on how many sides they span.

Q3: What are the applications of this calculation?
