1. What is Area of Equilateral Triangle of Hexagon given Inradius?

The Area of Equilateral Triangle of Hexagon given Inradius calculates the area of one of the equilateral triangles that form a regular hexagon when given the inradius (the radius of the circle inscribed within the hexagon).

2. How Does the Calculator Work?

The calculator uses the formula:

\[ A_{Equilateral\ Triangle} = \frac{\sqrt{3}}{3} \times r_i^2 \]

Where:

\( A_{Equilateral\ Triangle} \) — Area of one equilateral triangle (m²)
\( r_i \) — Inradius of the hexagon (m)
\( \sqrt{3} \) — Mathematical constant approximately equal to 1.732

Explanation: This formula derives from the relationship between the inradius of a regular hexagon and the side length of its constituent equilateral triangles.

3. Importance of This Calculation

Details: Calculating the area of equilateral triangles in a hexagon is essential in geometry, architecture, and engineering applications where hexagonal patterns are used. It helps in determining material requirements and structural properties.

4. Using the Calculator

Tips: Enter the inradius value in meters. The value must be positive (inradius > 0). The calculator will compute the area of one equilateral triangle that forms the hexagon.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between inradius and side length?
A: In a regular hexagon, the inradius \( r_i = \frac{\sqrt{3}}{2} \times a \), where a is the side length of the hexagon.

Q2: Can this formula be used for irregular hexagons?
A: No, this formula applies only to regular hexagons where all sides and angles are equal.

Q3: How is the total hexagon area related to this calculation?
A: A regular hexagon consists of 6 equilateral triangles, so total area = 6 × area of one equilateral triangle.

Q4: What are practical applications of this calculation?
A: Used in honeycomb structure design, tile patterns, bolt head calculations, and various engineering applications.

Q5: How accurate is this formula?
A: The formula is mathematically exact for regular hexagons and provides precise results when accurate measurements are input.
