Then evaluate surface area of a sphere in both coordinate systems.
You'll see something interesting if you actually do the computation.

The multi-year super-senior has nothing to say besides the stupid
question in which I have given the answers already more than once.

Then provide the posts where you drive the surface area of spheres of
constant r and t in both supposedly-different metrics.
