I am a carpenter atm but will start my education to be a construction supervisor which will take 4 years.

Recently I started taking math classes and just got my fist grade 7.4! (out of 10) So I was happy since I never had math before.

Anyways, Now I am at chapter 9 of my book and I frequently get asked to do formulas like;

V=4/3 . PI . R^3

Rewrite as R

Now since I am taking a speed course, my teacher doesn't really have the time to go step by step to solve the problem.

I was hoping somebody could help me with this.

Kind regards, Kees.
