A circle with centre (3, 4) passes through the origin.
If a point in the circle is (x, y), write the relation between x, y?

Let C be the circle with centre at (1, 1) and radius = 1. If T is the circle centred at (0, y), passing through origin and touching the circle C externally, then the radius of T is equal to :

Equation of the circle with centre on the y-axis and pussing through the origin und the point (2, 3) is :

The circle, which passes through the origin and whose centre lies on the line y = x and cutting the circle x^2+y^2-4x-6y+10 = 0 orthogonally is :

The circle passes through the point (1,2) and cuts the circle x^(2)+y^(2)=4 orthogonally, then the equation of the locus of the centre is

If a circle passes through the point (a, b) and cuts the circle x^2+y^2=p^2 orthogonally, then the equation of the locus of its centre is:

Find the equation of the circle which passes through the origin and belonges to the co-axial of circles whose limiting points are (1,2) and (4,3).

The equation of the circle having centre (1, 2) and passing through the point of intersection of the lines: 3x+y=14 and 2x+5y=18 is :

The equation of a circle with origin as centre and passing through the vertices of an equilateral triangle whose median is of length 3a is:

Centre of a circle Q is on the Y-axis. The circle passes through the points (0, 7) and (0, -1). If it intersects the positive X-axis at (P, 0), what is the value of ‘P’?
