document.write( "The small cone (which is the cut part of the large cone) is similar to the large cone.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The similarity coefficient (the ratio of corresponding linear dimensions) is  \"2%2F3\"   (counting smaller to larger).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It means that the smaller cone volume is  \"%282%2F3%29%5E3\" = \"8%2F27\"  of the volume of the large cone.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the volume of the resulting frustum is  \"1+-+8%2F27\" = \"%2827-8%29%2F27\" = \"19%2F27\" of the volume of the large cone.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus the value under the question is  \"54pi%2A%2819%2F27%29\" = \"38pi\".    ANSWER\r\n" );
