cylinder volume:
\n" ); document.write( "Pi*r^2*h = Pi*5^2*15 = 1178.10
\n" ); document.write( "cone volume:
\n" ); document.write( "Pi*r^2*h/3 = Pi*5^2*(15/3) = 392.70
\n" ); document.write( ":
\n" ); document.write( "A)Volume of wood removed: 1178.10-392.70 = subtract to get the answer
\n" ); document.write( "B)answer you got for A divided by 1178.10
\n" ); document.write( "
\n" );
