Question 1173721
.


Please look how your post appears at the forum.



----------


By the way,  if the volume is    {{{972*pi}}} cm^3,


then the solution and the answer by @ewatrrr   {{{2916*pi}}}    are both   I N C O R R E C T.


The correct solution is below



<pre>
    {{{(4/3)*pi*r^3}}} = {{{972*pi}}}


Canceling pi in both sides

    {{{(4/3)*r^3}}} = 972

    {{{r^3}}} = {{{(3/4)*972}}} = 729

    r = {{{root(3,729)}}} = 9.


    Surface area = {{{4*pi*r^2}}} = {{{4*pi*9^2}}} = {{{4*81*pi}}} ={{{324*pi}}}.    <U>ANSWER</U>.
</pre>

<U>The correct answer</U>  &nbsp;&nbsp;is  &nbsp;&nbsp;{{{324*pi}}}.


Solved.
