Question 707876
Look at what was done to h.  Undo it!


The righthand side only consists of factors.  Multiply left and right hand sides of the equation by the multiplicative inverse of {{{pi}}} and the multiplicative inverse or {{{r^2}}}. Perform any simplifications.  You now have solved for h.


DIVIDE BOTH SIDES BY {{{pi}}} AND {{{r^2}}}.
