\r\n" );
document.write( "The diameter (and the radius) of the cone decrease in 2 times when the height changed in 6 inches. \r\n" );
document.write( "\r\n" );
document.write( "It means that the total height of the entire/whole/full cone is 12 inches.\r\n" );
document.write( "\r\n" );

document.write( "It should be clear to you.\r\n" );
document.write( "If it is not clear, make a sketch and mark the dimensions.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now the volume of the frustum cone is the difference between the volume of the full cone and the volume of its upper (cut) part:\r\n" );
