Answer:

$(x+15)^2+(y-11)^2=4$

Step-by-step explanation:

The question is

How do you write an equation for a circle with center (-15,11) and radius 2?

we know that

The equation of a circle in center radius form is given by

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

where

(h,k) is the center of the circle

r is the radius of the circle

substitute the given vales

$(x+15)^2+(y-11)^2=2^2$

$(x+15)^2+(y-11)^2=4$
