The Circumsphere Radius of a Dodecahedron is the radius of the sphere that contains the dodecahedron in such a way that all the vertices are lying on the sphere. It represents the distance from the center of the dodecahedron to any of its vertices.
The calculator uses the formula:
Where:
Explanation: This formula establishes a direct proportional relationship between the face diagonal and the circumsphere radius of a regular dodecahedron.
Details: Calculating the circumsphere radius is crucial in geometry and 3D modeling for determining the spatial requirements of a dodecahedron, understanding its geometric properties, and for applications in crystallography, architecture, and mathematical analysis.
Tips: Enter the face diagonal of the dodecahedron in meters. The value must be positive and greater than zero. The calculator will compute the circumsphere radius using the mathematical relationship between these two geometric properties.
Q1: What is a regular dodecahedron?
A: A regular dodecahedron is a three-dimensional shape with 12 identical regular pentagonal faces, 20 vertices, and 30 edges.
Q2: How is the face diagonal related to the circumsphere radius?
A: The circumsphere radius is directly proportional to the face diagonal, with a constant factor of √3/2.
Q3: Can this formula be used for irregular dodecahedrons?
A: No, this formula applies only to regular dodecahedrons where all faces are identical regular pentagons.
Q4: What are practical applications of this calculation?
A: This calculation is used in molecular modeling, architectural design, game development, and mathematical research involving polyhedral geometry.
Q5: How accurate is this calculation?
A: The calculation is mathematically exact for regular dodecahedrons, with accuracy depending only on the precision of the input value.
