In each of the following, find the centre and radius of the circles.

(x + 5)2 + (y – 3)2 = 36

The equation of the given circle is (x+5)2 +(y-3)2 = 36.


(x+5)2 +(y-3)2 = 36


+ (y - 3)2 =62, which is of the form (x – h)2 + (y – k )2 = r2,


Where, h =-5, k =3 and r= 6.


Thus, the centre of the given circle is (-5, 3), while its radius is 6.
