Question 17655
{{{V=(4/3)*pi*r^2*h}}}


Multiply both sides of the equation by the denominator, which is 3, to eliminate the denominator in the equation:
{{{3*V= 3*(4/3)*pi*r^2*h}}}
{{{3V = 4*pi*r^2*h}}}


Now to solve for h, you need to "undo" everything that has been done to the h.  That is, you multiplied by all those other factors:  {{{4*pi*r^2}}}.  So you need to DIVIDE by those factors in order to undo the multiplications:

{{{(3V)/(4*pi*r^2) = (4*pi*r^2*h)/(4*pi*r^2)}}}

{{{(3V)/(4*pi*r^2) = h}}}
