A circle is tangent to the x and y axes in the first quadrant at the points P and Q respectively. BC and AD are parallel tangents to the circle with slope −1. If the points A and B are on the y- axis while C and D are on the x-axis and the area of the quadrilateral ABCD is 900√2 sq. units, then the radius of the circle is
