Hey mate ^_^
The equation derived using the Newtonian approach is exactly the same as the first Friedmann equation whether k is zero or non-zero....
Whether there's any great insight to be had here is debatable, but it's certainly an interesting result...

In the derivation of Newtonian Cosmology, We use.........
M(r)=4π3ρr3M(r)=4π3ρr3
But this formula is based on volume of sphere in Euclidean geometry. If Universe would be curved the volume is different in say Spherical or Hyperbolic geometry. As a two dimensional example, the area of a circle of radius rr on a 2-sphere of radius RRis given by.........
A(r)=2πR2(1−cosrR)
Hope it helps
