You can put this solution on YOUR website!
\"system%28h%2Api%2Ar%5E2=28%2Cs=surfaceArea%2Cs=h%2A2pi%2Ar%2B2%2Api%2Ar%5E2%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You are interested in finding the minimum s.
\n" ); document.write( "You said, you have r, but want h. Use your volume equation. You can find r in terms of h, or you can find h in terms of r. It is your choice which you choose. You want s as a function of one variable.\r
