Equation of circle : (x-h)² + (y-k)² = R², where h and k are the coordinates of the circle and R, THE RADIUS
Center coordinates (5,-4), hence
(x-5)² + (y+4)² =R²
Now let's calculate R. Just replace x and y by the coordinates (-3,2)
(-3-5)² + (2+4)² = 10², so the Radius is equal to 10 and the final shape:
(x-5)² + (y+4)² = 100
