1. What is Circumsphere Radius of Icosidodecahedron?

The Circumsphere Radius of an Icosidodecahedron is the radius of the sphere that contains the Icosidodecahedron in such a way that all the vertices are lying on the sphere. It is an important geometric property of this Archimedean solid.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ r_c = \frac{(1 + \sqrt{5}) \times h_{Triangle}}{\sqrt{3}} \]

Where:

\( r_c \) — Circumsphere Radius of Icosidodecahedron (m)
\( h_{Triangle} \) — Triangular Face Height of Icosidodecahedron (m)
\( \sqrt{5} \) — Square root of 5 (approximately 2.23607)
\( \sqrt{3} \) — Square root of 3 (approximately 1.73205)

Explanation: This formula relates the circumsphere radius to the height of the triangular faces through the golden ratio and geometric constants.

3. Importance of Circumsphere Radius Calculation

Details: Calculating the circumsphere radius is essential for understanding the spatial dimensions of the icosidodecahedron, which has applications in architecture, crystallography, and mathematical modeling of complex structures.

4. Using the Calculator

Tips: Enter the triangular face height in meters. The value must be positive and non-zero.

5. Frequently Asked Questions (FAQ)

Q1: What is an Icosidodecahedron?
A: An icosidodecahedron is an Archimedean solid with 32 faces (20 triangles and 12 pentagons), 30 identical vertices, and 60 edges.

Q2: Why is the golden ratio (√5) present in the formula?
A: The icosidodecahedron's geometry is closely related to the golden ratio, which appears naturally in its proportions and dimensions.

Q3: What are typical values for the triangular face height?
A: The triangular face height depends on the specific size of the icosidodecahedron, but it's typically proportional to the edge length of the polyhedron.

Q4: Can this formula be used for other polyhedra?
A: No, this specific formula applies only to the icosidodecahedron due to its unique geometric properties.

Q5: How accurate is this calculation?
A: The calculation is mathematically exact, assuming precise input values and proper implementation of the formula.
