Question 53572
Find the radius of each sphere described.
:
I don't know that TT is but assuming the vol is in cu units 
Volume = 4.5 TT
:
V = {{{4/3}}}*pi*r^3
:
:
{{{4/3}}*pi*r^3 = 4.5
:
Get rid of the denominator, mult eq by 3 and you have:
4 * pi * r^3 = 13.5
:
r^3 = {{{13.5/4pi}}}
 
Surface area = 144 TT
