The question asks for the volume of the cylinder MINUS the cone. The heights of both shapes are equal. Cylinder of diameter 12 has a hole drilled of diameter of base circle 3; and heights of both are equal.\r

\n" ); document.write( "\n" ); document.write( "Volume of cylinder: formula, \"v=h%2Api%2Ar%5E2\"
\n" ); document.write( "Your example, h=15, r=6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Volume of cone: formula, \"v=%281%2F3%29h%2Api%2Ar%5E2\"
\n" ); document.write( "Your example, h=15, r=3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The volume asked is \"highlight_green%2815%2Api%2A6%5E2-%281%2F3%29%2A15%2Api%2A3%5E2%29\".
