You can put this solution on YOUR website!
You can evaluate the volume, and then use formula for volume of a cone to calculate the unknown height.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Cone: you know r for radius but do not know h for height.\r

\n" ); document.write( "\n" ); document.write( "The volumes, v, are equal.\r
\n" ); document.write( "

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"h=4r%5E3%2Fr%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"highlight%28h=4r%29\", using then r=2, find h=8.
