The formula for the area of a circle is:
\n" ); document.write( "\"A+=+pi%2Ar%5E2\"
\n" ); document.write( "The diameter = 20 in. WE want radius, which is 1/2 diameter or 10 in. So,
\n" ); document.write( "\"A+=+pi%2A10%5E2\"
\n" ); document.write( "\"A+=+100pi\"
\n" ); document.write( "A ~ 314.2 in^2
\n" ); document.write( "
\n" );
