You can put this solution on YOUR website!
V = 2πrh\r
\n" ); document.write( "\n" ); document.write( "121 = 2πrh\r
\n" ); document.write( "\n" ); document.write( "h=121/2πr\r
\n" ); document.write( "\n" ); document.write( "h=60.5/πr\r
\n" ); document.write( "\n" ); document.write( "r=3\r
\n" ); document.write( "\n" ); document.write( "h=60.5/3π\r
\n" ); document.write( "\n" ); document.write( "h=6.42
