WebHello, welcome to my channel, Rhombus :)Today's video explains how you can figure out the radius of the sphere using the inscribed tetrahedron's edge length.... WebMay 22, 2024 · Thus, since the radius of the sphere lay on the altitude of the tetrahedron, all I needed to find was the ratio of the altitude of the tetrahedron to the radius of the sphere. To do so, I simplified the problem into 2 dimensions, and used the formulas A=bh, & A=rs to solve for the in-radius, r. I then divided the in-radius r, over the altitude ...
WebThe sphere is inscribed in the tetrahedron, hence the length of the perpendicular from the centre (a, b, c) upon each of the faces = radius of the sphere ∴ 1 a = 1 b = 1 c = 1 + 4 + 4 1 … WebMar 24, 2024 · The Reuleaux tetrahedron, sometimes also called the spherical tetrahedron, is the three-dimensional solid common to four spheres of equal radius placed so that the center of each sphere lies on the surface of the other three. The centers of the spheres are therefore located at the vertices of a regular tetrahedron, and the solid consists of an …
WebThe total surface area of a regular tetrahedron is: Total Surface Area = √3s 2 Substituting 's' = 6, we get: Total Surface Area = √3 × 6 2 = √3 × 6 × 6 = 62.35 Therefore, the total surface area of the tetrahedron is 62.35 square units.
