For the cylinder alone:
\n" ); document.write( "\"+A%5B1%5D+=+pi%2A2%5E2%2A10+\"
\n" ); document.write( "\"+A%5B1%5D+=+40pi+\"
\n" ); document.write( "--------------------------
\n" ); document.write( "For the 2 ends:
\n" ); document.write( "\"+A%5B2%5D+=+2%2Api%2A2%5E2+\"
\n" ); document.write( "\"+A%5B2%5D+=+8pi+\"
\n" ); document.write( "---------------------------
\n" ); document.write( "\"+A%5B1%5D+%2B+A%5B2%5D+=+48pi+\"
\n" ); document.write( "The answer is B)
