1.	If the radius of the circumcircle of the triangle TPQ, where PQ is chord of contact corresponding to point T with respect to circle x2+y2−2x+4y−11=0, is 6 units, then minimum distance of T from the director circle of the given circle is
Answer» If the radius of the circumcircle of the triangle $T P Q$ , where $P Q$ is chord of contact corresponding to point $T$ with respect to circle $x^{2} + y^{2} - 2 x + 4 y - 11 = 0$ , is $6$ units, then minimum distance of $T$ from the director circle of the given circle is
