The equation of circle is (x+8)^2+(y+9)^2=9 .

Step-by-step explanation:

It is given that the diameter of circle is 6 units and the center of circle is (-8,-9).

The standard form of a circle is

(x-h)^2+(y-k)^2=r^2

Where, (h,k) is center of the circle and r is radius.

The diameter of circle is twice of its radius

d=2r

6=2r

r=3

The radius of the circle is 3 and the center of circle is (-8,-9). So, the required equation of circle is

(x-(-8))^2+(y-(-9))^2=3^2

(x+8)^2+(y+9)^2=9

Therefore the equation of circle is (x+8)^2+(y+9)^2=9 .
