A square is inscribed in the circle x^2+y^2-2 x+4 y-93=0 with its sides parallel to the co-ordinate axes. Then which among the following can be one of the vertices of the square?

Options

  1. A(5,8)
  2. B(8,5)
  3. C(8,-5)
  4. D(-8,5)

Correct answer

B. (8,5)

Step-by-step solution

Equation of given circle is gathered x^2+y^2-2 x+4 y-93=0 (x-1)^2+(y+2)^2=98 gathered The vertex of the square inscribed in the circle whoses sides are parallel to the coordinate axes is aligned & (1 98 4 ,-2 98 4 ) &=(1 7,-2 7) &=(8,5),(8,-9),(-6,5),(-6,-9) aligned
