both circles have the same center, and the radius of the larger circle is r. if the radius of the smaller circle 3 units less than r, which of the following represents the areas of the shaded regions?
\n" ); document.write( "==============
\n" ); document.write( "Nothing followed.
\n" ); document.write( " $\"Area+=+pi%2Ar%5E2+-+pi%2A%28r-3%29%5E2\"$
\n" ); document.write( "= $\"pi%2A%286r+-+9%29\"$ for r >= 3
\n" ); document.write( "===============
\n" ); document.write( "PS It's not necessary that they have the same center. \n" ); document.write( "

\n" );
