sir length of tangent =√s1 se kiya toh alag ans aa rga h
bhaiya in yourv1st que the que can also be done easily by parametric form the angle be the tangents is 60 so the angle be the radius joining will be 120...hence we can do it easily by there also......I think so
the locus of equation is x^2+y^2-2r^2=0 therefore radius=(2^1/2)r
x² + y² = (r√2)² and radius is r√2
