r in terms of V and pi.
Simple algebra steps. SIMPLE algebra!!

BEGINNING, V=%284%2F3%29pi%2Ar%5E3

Undo the factors %284%2F3%29 and pi.
V%283%2F4%29%2A%281%2Fpi%29=%284%2F3%29pi%2Ar%5E3%2A%283%2F4%29%2A%281%2Fpi%29
%283V%29%2F%284pi%29=r%5E3

Undo the exponent of 3 on r.
%28r%5E3%29%5E%281%2F3%29=%28%283V%29%2F%284pi%29%29%5E%281%2F3%29

r=root%283%2C%28%283V%29%2F%284pi%29%29%29
