Another question regarding spheres:

Is it true that $|S_{n}| = O( \frac{1}{\sqrt n} )$ ?

(I mean the surface area of the n dimensional sphere) Thanks !

    I did... I know the formula for the surface area of the sphere, but just wondering if this gamma function can be approximated in a way that will give us that the surface area is $O(\frac{1}{\sqrt n } ) $ . Hope I formulated it in a clearer way now.2012-07-23
