Left argument is the radius of the "n-sphere". Right argument is the number of dimensions. I put "n-volume" in quotes, because if the dimension is 2 (for example), the "n-volume" is what we call the area of the circle. (And if the dimension is 1 that "n-volume" is the length of a line segment). Anyways, I stumbled across this and thought it might be interesting for someone else.
