So the question or problem ask to find the equation of a circle which has a center of (-1,2) and a radius of 3 units. To get the equation of the circle, you must first follow the formula which is (x-h)^2 +(y-k)^2 = r^2. So the answer would be letter D. (x+1)2+(y-2)2=9. I hope you are satisfied with my answer
