S = 2 pi r (r+h)
\n" ); document.write( "200 = 2 pi h/2 (h/2+h)
\n" ); document.write( "h = 6.5147
\n" ); document.write( "diameter =h
\n" ); document.write( "or
\n" ); document.write( "diameter/2=radius=6.5147/2
\n" ); document.write( "200 = 2 pi r (r+2r)
\n" ); document.write( "r = 3.2574
\n" ); document.write( "
\n" ); document.write( "
