Polar equations of the circle for the given coordinate (x,y) which satisfies the equation given by (x-a)2+(y-b)2=r2 where (a,b) is the coordinates of the centre of the circle &r is the radius.

• A. x = r cos u2061 , y = r sin u2061
• B. x = a+ r cos u2061 , y = b + r sin u2061
• C. y = a+r cos u2061 , x = b + r sin u2061
• D. x = r sin u2061 , y = r cos u2061
