The parametric equations of circle (x-3)^{2}+(y-2)^{2}=100 are

The point (-1, 0) lies on the circle x^{2}+y^{2}-4x+8y+k=0. The radius of the circle

The lengths of the chords of the circle x^{2}+y^{2}-2x-6y-15=0 which make an angle of 60^{0} at (1, 3) and the locus of the midpoints of all such chords are

The shortest distance from (-2, 14) to the circles x^{2}+y^{2}-6x-4y-12=0 is

If the distances from the origin to the centres of three circles x^{2}+y^{2}-2k, x=c^{2} (i=1,2,3),are in G.P, then the lengths of the tangents drawn to them from any point on the circle x^{2} + v^{2} = c^{2} are in
