find an equation of the circle whose diameter has endpoints (3, -5) and (3, 1).
\n" ); document.write( "
Center of circle: (3, - 2)
\n" );
document.write( "\"%28x+-+h%29%5E2+%2B+%28y+-+k%29%5E2+=+r%5E2\" ------ Center-radius form of equation of circle
\n" );
document.write( "\"%283+-+3%29%5E2+%2B+%281+-+-+2%29%5E2+=+r%5E2\" -------- Substituting point (3, 1) for (x, y) and center (3, - 2) for (h, k)
\n" );
document.write( "\"9+=+r%5E2\" ======> r 
\n" );
document.write( "Equation of circle: \"highlight_green%28%28x+-+3%29%5E2+%2B+%28y+%2B+2%29%5E2+=+9%29\"
