Circle with centre C (1, 1) passes through the origin and intersects the x-axis at A and y-axis at B. The area of the part of the circle that lies in the first quadrant is

The equation of the smallest circle passing through the point (1,0) and (0,1) is

If |z|lt1, then 1+2z lies (A) on or inside circle having center at origin and radius 2 (B) outside the circle having center at origin and radius 2 (C) inside the circle having center at (1,0) and radius 2 (D) outside the circle having center at (1,0) and radius 2.

The centre of a circle is (2x-1, 3x++1) and radius is 10 units. Find the value of x if the circle passes through the point (-3, -1) .
