My friend, there is no figure, so I will assume that we are talking about a semicircle and a diameter and the shaded area is the inside.\r
\n" ); document.write( "\n" ); document.write( "The area of the shaded figure is half of the area of the circle, that is,
\n" ); document.write( "\"A+=+%281%2F2%29%2Api%2Ar%5E2+=+%281%2F2%29%2A3.14%2A3%5E2+=+14.13\"\r
\n" ); document.write( "\n" ); document.write( "The perimeter is that of a semicircle plus the length of the diameter:\r
\n" ); document.write( "\n" ); document.write( "\"P=%281%2F2%29%2A2%2Api%2Ar%2B2%2Ar+=+3.14%2A3%2B6+=+15.42\"
\n" ); document.write( "
\n" );
