Some inequalities on the inradii of a simplex and of its faces
The authors give two interesting inequalities between the inradius of an \(n\)-dimensional simplex and those of \(n - 1\)-dimensional faces. As application, they prove some inequalities that connect the \(n\)-volume of a simplex and the \(n - 1\)-volumes of faces.
