A circular mirror is surrounded by a square metal frame.
\n" ); document.write( " The radius of the circular mirror is 3x.
\n" ); document.write( " The side length of the metal frame is 15x.
\n" ); document.write( " What is the area of the metal frame?
\n" ); document.write( ":
\n" ); document.write( "Find the area of the whole thing:
\n" ); document.write( "(15x)^2 = 225x^2
\n" ); document.write( ":
\n" ); document.write( "Find the area of the mirror
\n" ); document.write( "\"pi%2A%283x%29%5E2+=+28.27x%5E2\"
\n" ); document.write( ":
\n" ); document.write( "Find the metal area surrounding the mirror
\n" ); document.write( "225x^2 - 28.27x^2 = 196.73x^2
\n" ); document.write( "
\n" );
