Answer:

The equation of the circle having centre (-5,-9) and radius r=3 is

x² + 10 x +y² + 14 y + 65 = 0

Explanation:

Explanation:-

From graph The centre of the circle C( -5 , -7)

The radius of the circle r = 3cm from the centre of the given circle

The equation of the circle



From graph the centre ( h, k) = ( -5,-7) and r = 3cm


(x-(-5))^2+(y-(-7))^2 = 3^2

x² + 10 x +25 +y² + 14 y + 49 =9

x² + 10 x +25 +y² + 14 y + 49 -9=0

The equation of the circle

x² + 10 x +y² + 14 y + 65 = 0
