Then the radius of the circle isWhich of the following straight lines are both tangent to the circle x2+y2−6x+4y−12=0x ^ 2 + y ^ 2 - 6x + 4y - 12 = 0x2+y2−6x+4y−12=0?In the xy-plane let A=(−2,0),B=(2,0)A = (- 2, 0), B = (2, 0)A=(−2,0),B=(2,0) . Define the set S as the collection of all points C on the circle x2+y2=4x ^ 2 + y ^ 2 = 4x2+y2=4 such that the area of the triangle ABC is an integer. The number of points in the set S is
