Question

The equation of circle with centre (1,1) and radius 4 is given by (x1)2 + (y1)2 = 4


  1. True

  2. False


Solution

The correct option is B

False


The centre of the circle is O(1,1) and radius is 4 units. Let us consider a general point P on the circle. Let the co-ordinates of the point P be (x,y).

PO=4

 (x1)2 + (y1)2 = 4

 (x1)2 + (y1)2 = 16 is the equation of the circle.
