document.write( "The water in the bottom of the hemispheric bowl is a spherical cap, and the\r\n" );
document.write( "formula for its volume is\r\n" );

document.write( "Volume of a spherical cap = \"expr%281%2F3%29%2Api%2Ah%5E2%283R+-+h%29\", where h=9 cm. is the\r\n" );
document.write( "height of the spherical cap (water), and radius R = 21 cm. (half the 42 cm\r\n" );

document.write( "This is a hemisphere, not a whole sphere, so remember that the volume of a\r\n" );
document.write( "hemisphere is only 1/2 the volume of a whole sphere.\r\n" );
document.write( "\r\n" );
document.write( "So you only need to calculate those two volumes and subtract them to find the\r\n" );
