If `|(z-2)//(z-3)|=2` represents a circle, then find its radius.

Show that |(z -2)/(z - 3)| = 2 represents a circle, find its centre and radius.

If Im((iz+2)/(z+i))=-1 represents part of a circle with radius r units, then the value of 4r^(2) is (where, z in C, z ne i,lm(z) represents the imaginary part of z and i^(2)=-1 )

The equation zbarz+(4-3i)z+(4+3i)barz+5=0 represents a circle of radius

The equation |z-1|^(2)+|z+1|^(2)=2 represents (1) a circle of radius 1(2) a straight line (3) the ordered pair (0,0)(4) none of these

Show that the locus of complex variable z satisfying |(z-2)/(z+2)|=2 is a circle find the equation of the circle?

If z be a complex number, then |z-3-4i|^(2)+|z+4+2i|^(2)=k represents a circle, if k is equal to

z bar(z)+(3-i)z+(3+i)bar(z)+1=0 represents a circle with
