The generic equation of the circle is:
 (x-xo) ^ 2 + (y-yo) ^ 2 = r ^ 2
 Where,
 (xo, yo): coordinate of the center of the circle
 r: radius of the circle.
 Substituting values we have:
 (x-9.2) ^ 2 + (y + 7.4) ^ 2 = (5/3) ^ 2
 Rewriting:
 (x-9.2) ^ 2 + (y + 7.4) ^ 2 = 25/9
 Answer:
 The equation of the circle is:
 (x-9.2) ^ 2 + (y + 7.4) ^ 2 = 25/9
