The equation of a circle is \"%28x-h%29%5E2+%2B+%28+y-k%29%5E2+=+r%5E2\"
\n" ); document.write( "(h,k) is the coordinate for the center of the circle.


\n" ); document.write( "-h = 2 so h = -2 and -k = -4 so k=4. The center is (-2,4)


\n" ); document.write( "\"r%5E2+=+225\". \"sqrt%28225%29+=+15\"


\n" ); document.write( "The correct choice is A. \n" ); document.write( "

\n" );
