Sorry can't help you there but how about an additional question:
the formula for the 3D volume of a 4 dimensional sphere? This would be analogous to the area of a 3D sphere.
Well in anwser to these little questions:

(Yikes can't use links with brackets!!!! DOT is a ".")
1. A hypersphere (4D sphere) has a 4D "Area" of
V4 = π
2r
4/2
2. A hypersphere (4D sphere) has a 3D "Surface" of
S3 = 2π2r3
