What is your attempt to deal with the problem? You searched examples or counterexamples?

comment Why $\int_{\mathbb R^n}e^{-\sum_{i=1}^n x_i^2} \, dx_1\cdots dx_n=\omega_{n-1}\int_0^\infty e^{-r^2}r^{n-1} \, dr$
Did you mean that $\sum_{i=1}^1 x_i^2=1$ rather than $\sum_{i=1}^1 x_i=1$ ?

Did you mean that $\omega_{n-1}$ is the area of surface rather than $\omega_{n-1}$ be the surface?
