Ex 11.1, 6 Find the centre and radius of the circle (x + 5)2 + (y – 3)2 = 36 Given (x + 5)2 + (y – 3)2 = 36 (x – (–5))2 + (y – 3)2 = 36 We know that Circle of equation is given by (x – h)2 + (y – k)2 = r2 Comparing (1) & (2) h = –5, k = 3, r2 = 36 Thus, centre of circle = (h, k) = (−5, 3) & Radius = r = 6
