Answer

A\text{A}

Step-by-step solution

4 steps
  1. Identify the center and a point on the circle.

    The center of the circle is (h,k)=(1,1)(h, k) = (1, 1).
    The circle passes through the point (x,y)=(2,−3)(x, y) = (2, -3).

  2. Calculate the radius of the circle.

    The radius rr is the distance between the center and the point on the circle. We use the distance formula: r=(x2−x1)2+(y2−y1)2r = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}.

    r=(2−1)2+(−3−1)2r = \sqrt{(2 - 1)^2 + (-3 - 1)^2} r=(1)2+(−4)2r = \sqrt{(1)^2 + (-4)^2} r=1+16r = \sqrt{1 + 16} r=17r = \sqrt{17}
  3. Calculate the diameter of the circle.

    The diameter DD is twice the radius.

    D=2rD = 2r D=217D = 2\sqrt{17}
  4. Match the result with the given options.

    The calculated diameter is 2172\sqrt{17}, which corresponds to option (A).

    The final answer is A\text{A}.
