The correct options are
A (8, 5)
C (–6, 5)
D (–6, –9)
Radius and center of the circle are (1, –2) and
7√2 respectively
Thus diameter of the circle is
14√2 and is equal to diagonal of the square, hence each side of square is 14. Since each side of the square are parallel to axes, let its equation be
x=a, x =b, y =c, y =d
also, r distance from center to each side of the circle
=7
This gives a = –6, b = 8, c =–9, d = 5
So vertices are (8, 5), (8, –9), (–6, 5), (–6, –9)
