The center(s) of the circle(s) passing through the points (0, 0) and (1, 0) and touching the circle x^2+y^2=9 is (are)

The circle which can be drawn to pass through (1, 0) and (3, 0) and to touch the y-axis intersect at angle thetadot Then costheta is equal to (a) 1/2 (b) -1/2 (c) 1/4 (d) -1/4

Equation of the smaller circle that touches the circle x^2+y^2=1 and passes through the point (4,3) is

The circle passing through the point (-1,0) and touching the y-axis at (0,2) also passes through the point:

A circle passes through the points A(1,0)a n dB(5,0), and touches the y-axis at C(0,h)dot If /_A C B is maximum, then

Find the equations of the circles passing through the point (-4,3) and touching the lines x+y=2 and x-y=2

Radius of the circle that passes through the origin and touches the parabola y^2=4a x at the point (a ,2a) is (a) 5/(sqrt(2))a (b) 2sqrt(2)a (c) sqrt(5/2)a (d) 3/(sqrt(2))a

The line x = y touches a circle at the point (1, 1). If the circle also passes through the point (1, -3). Then its radius is 0
