Radius of the largest circle passing through the focus of the parabola y^2 = 4x and lying inside the parabola is…

The focus of the parabola y ^(2) =4y -4x is

The radius of circle which passes through the focus of parabola x^(2)=4y and touches it at point (6,9) is k sqrt(10), then k=

The focus of the parabola y^(2)-4y-8x+4=0 is,

The radius of the circle, which touches the parabola y^2 = 4x at (1,2) and passes through the origin is:

A circle touches the parabola y^(2)=4ax at P. It also passes through the focus S of the parabola and intersects its axis at Q. If angle SPQ is 90^(@), find the equation of the circle.
