If the centroid of an equilateral triangle is (1, 1) and its one vertex is (-1, 2), then the equation of the circumcentre is :

If the centroid of an equilateral triangle is (2, -2) and its one vertex is (-1, 1) , then the equation of its circumcircle is

If the centroid of an equilateral triangle is (2, -2) and its one vertex is (-1, 1) , then the equation of its circumcircle is

If the centroid of an equilateral triangle is (1,1) and its one vertex is (2,-1) , then equation of the circumcircle of the triangle is

If the centroid of an equilateral triangle is (1,1) and its one vertex is (-1,2) then the equation of the circumcircle is

If the incentre of an equilateral triangle is (1,1) and the equation of its one side is 3x+4y+3=0 then the equation of the circumcircle of the triangle is

Two vertices of an equilateral trianglt are (-1,0) and (1,0) and its third vertex is above the x -axis. The equation of its circum circle is

Two vertices of an equilateral triangle are (-1,0) and (1,0), and its third vertex lies above the x-axis.The equation of its circumcircel is
