							We can solve this problem by letting a line parallel to the line given in the question...  We know equation of line parallel to 4x+3y+5=0 is 4x +3y+k=0..  Where k is a constant...  Let us suppose that this line is the tangent to the circle...  Since it is a tangent to the circle therefore the perpendicular distance from the centre of circle is equal to its radius...  Use this method and get the answer...  Hope U like it
