Actually, you have no chance to find ComputeApproximateSquaredLength_3 
by grepping the source code files, since it is the name of a concept.

But if you read the manual, you will see that
CGAL::Spherical_kernel_3 is a model of SphericalKernel

Then you should normally find that
SphericalKernel::Compute_approximate_squared_length_3
is a model of SphericalKernel::ComputeApproximateSquaredLength_3.

But there is a bug in the manual, since it is written
SphericalKernel::ComputeApproximateSquaredLength_3
instead of
SphericalKernel::Compute_approximate_squared_length_3
I am going to fix this, it will be corrected in the next CGAL release.
