The area of the sheet is:
\n" ); document.write( "\"+36%2A25+=+900+\" cm2
\n" ); document.write( "----------------------
\n" ); document.write( "The radius of the buttons is:
\n" ); document.write( "\"+d%2F2+=+3.5%2F2+\"
\n" ); document.write( "\"+d%2F2+=+1.75+\" cm
\n" ); document.write( "-------------------
\n" ); document.write( "The area of each button is:
\n" ); document.write( "\"+A+=+pi%2Ar%5E2+\"
\n" ); document.write( "\"+A+=+3.141%2A1.75%5E2+\"
\n" ); document.write( "\"+A+=+9.619+\" cm2
\n" ); document.write( "--------------------
\n" ); document.write( "The total area of \"+56+\" buttons is:
\n" ); document.write( "\"+56%2A9.619+=+538.682+\" cm2
\n" ); document.write( "----------------------------
\n" ); document.write( "The area left over is:
\n" ); document.write( "\"+900+-+538.682+=+361.319+\" cm2
\n" ); document.write( "
\n" ); document.write( "
\n" );
