Solution

The correct options are
A (8, 5)
C (–6, 5)
D (–6, –9)
Radius and center of the circle are (1, –2) and 72 respectively
Thus diameter of the circle is 142 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)
