1. What is the Edge Length of Tetrahedron given Circumsphere Radius?

The edge length of a tetrahedron can be calculated from its circumsphere radius using the mathematical relationship between these two geometric properties. This calculation is essential in geometry and 3D modeling applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \sqrt{\frac{2}{3}} \) — Square root of two-thirds
• Circumsphere Radius — Radius of the sphere that contains all vertices of the tetrahedron

Explanation: The formula establishes a direct proportional relationship between the edge length and circumsphere radius of a regular tetrahedron.

3. Importance of Edge Length Calculation

Details: Calculating edge length from circumsphere radius is crucial for geometric modeling, structural design, and understanding the spatial properties of tetrahedral shapes in various engineering and mathematical applications.

4. Using the Calculator

Tips: Enter the circumsphere radius in meters. The value must be positive and valid for accurate calculation of the edge length.
