1. What is Inradius of Dodecagon?

The inradius of a dodecagon (12-sided polygon) is the radius of the circle that fits perfectly inside the dodecagon, touching all its sides. It represents the distance from the center to any side of the regular dodecagon.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( r_i \) — Inradius of the dodecagon
• \( d_6 \) — Diagonal across six sides of the dodecagon
• \( \sqrt{3} \) — 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 inradius based on the diagonal measurement that spans six sides of the regular dodecagon.

3. Importance of Inradius Calculation

Details: The inradius is crucial in geometry for determining the size of the largest circle that can fit inside a dodecagon, calculating area, and understanding the spatial relationships within the polygon.

4. Using the Calculator

Tips: Enter the diagonal across six sides measurement in meters. The value must be positive and greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a dodecagon?
A: A dodecagon is a polygon with twelve sides and twelve angles. When regular, all sides and angles are equal.

Q2: How is diagonal across six sides measured?
A: It's the straight line distance between two non-adjacent vertices that are six sides apart on the dodecagon.

Q3: What are typical applications of this calculation?
A: Used in architecture, engineering design, geometric modeling, and various mathematical applications involving regular polygons.

Q4: Can this formula be used for irregular dodecagons?
A: No, this formula applies only to regular dodecagons where all sides and angles are equal.

Q5: How accurate is this calculation?
A: The calculation is mathematically precise for regular dodecagons, with accuracy depending on the precision of the input measurement.
