Answer 1

I am giving hint

find the centre of the given circle equation that point is equal to the centre of the required circle equation because they both are concentric circles then the circles have same center point as shown in fig

then find the perpendicular distance from center to the given line which gives the length of the radius , because here given line equation touches the required circle as shown in fig it means that the line is a tangent to the required circle.

then use the general circle equation

(x-h)^2+(y-k)^2=r^2

you have substitute the centre point and value of radius in (h,k) and r to get the equation of required circle equation
