Answer:

(x-2)²+(y+3)²=9

Explanation:

We know that the formula for the area of the circle is:

(x-h)²+(y-k)²=r²

-h,k being the center coordinates

-r being the radius

In this case, (2,-3) are the center coordinates and 3 the radius, so simply plug these into the equation giving us:

(x-2)²+(y+3)²=9
