Radius of circumscribed sphere tetrahedron

WebSep 21, 2014 · B2 = φB1, so, by the Pythagorean Theorem, (2R1)^2 = (B1)^ + φ² (B1)², which simplifies to 4 (R1)^2 = (1 + φ²) (B1)^2, which can then be solved for B1 as B1 = sqrt [4 (R1)^2/ (1 + φ²)]. B1 here is the icosahedron’s edge-length, while R1 is the radius of its circumscribed sphere. Dodecahedron: find B1, in terms of Y2.
