This is practice questions for my exam, and I need help

There are cosmological models which see our universe as a 4-dimensional
sphere which expands in space-time. Assume the volume V = n²r4, where r is in
dV
= 100n?r2. At what rate is the radius of
dt
billion light years, increases at a rate of
the universe increasing when the radius is 47 billion light years?
