How many coordinates we need to remove from a uniformly selected point on the unit sphere before the remaining are on the same order of magnitude?

Picking points on a sphere at random

Connection between the area of a n-sphere and the Riemann zeta function?

What is the metric on the $n$-sphere in stereographic projection coordinates?

If the Greeks had been four dimensional, would they have been able to derive the pi squared coefficient for the hypersphere volume without calculus?

What is $\mathcal{R}$?
