document.write( "(a)  By answering question (a), you should subtract the volume of the half-sphere from the volume of  7*12*2 cubic centimeters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "(b)  When you complete part (a), the answer to part (b) will be SAME VOLUME added as the answer to the part (a).\r\n" );
