Question 1034529
.
<pre>
If you are talking/asking about a sphere, then its volume is 

V = {{{(4/3)*pi*r^3}}},

where "r" is its radius.

If you have given V = {{{33*pi}}}, it means that

{{{(4/3)*pi*r^3}}} = {{{33*pi}}}.

Cancel the factor {{{pi}}} in both sides. You will get

{{{(4/3)*r^3}}} = {{{33}}}.

Then  {{{r^3}}} = {{{(3*33)/4}}} = {{{24.75}}}  and 

r = {{{root(3, 24.75)}}} = 2.914 (approximately).
