# What is the shortest distance between (-2,0) and (2,0) without entering Inside of the circle x^2+y^2=1 ?1.  2√32.  2√3+π/33.  √3+2π/34.  None of these

Length of tangent will be $\sqrt{}$S(-2,0) which will when doubled give the exact length where S= x2+y2=1
2* $\sqrt{}\frac{}{}$(-2)+0 -1 = 2$\sqrt{}$3
