The standard form of the equation for a circle with its center at (h, k) and radius of r is:
\n" ); document.write( " $\"%28x-h%29%5E2%2B%28y-k%29%5E2+=+r%5E2\"$ Comparing this with the given equation:
\n" ); document.write( " $\"%28x-3%29%5E2%2B%28y%2B4%29%5E2+=+25\"$
\n" ); document.write( "You can readily see that the center is: (3, -4) and the radius is: $\"r+=+sqrt%2825%29\"$ or $\"r+=+5\"$ \n" ); document.write( "
