*Write the equations of the circle that satisfies each set of conditions*\r
\n" ); document.write( "\n" ); document.write( "1) The circle passes through (7,-1) and has its center at (-2,4).
\n" ); document.write( "------------------
\n" ); document.write( "The distance from the center to the point is the radius.
\n" ); document.write( "Find the distance.
\n" ); document.write( "\"r%5E2+=+diffy%5E2+%2B+diffx%5E2+=+5%5E2+%2B+9%5E2\"
\n" ); document.write( "\"r%5E2+=+106\"
\n" ); document.write( "------------
\n" ); document.write( "A circle's equation with the center at (h,k) & radius r is
\n" ); document.write( "\"%28x-h%29%5E2+%2B+%28y-k%29%5E2+=+r%5E2\"
\n" ); document.write( "==============================
\n" ); document.write( "\"%28x%2B2%29%5E2+%2B+%28y-4%29%5E2+=+106\" is the circle.
\n" ); document.write( "
\n" );
