1.	which one of the following statements are correct? 1) Equation of a circle with centre (h,k) and radius r is given by (x−h)2 + (y−k)2 = r2 2) Equation of circle with A(x1,y1) and B(x2,y2) as extremities of diameter is given by (x−x1)(y−y1)+(x−x2)(y−y2)=0
Answer» which one of the following statements are correct? 1) Equation of a circle with centre $(h, k)$ and radius r is given by $(x - h)^{2} + (y - k)^{2} = r^{2}$ 2) Equation of circle with $A (x_{1}, y_{1})$ and $B (x_{2}, y_{2})$ as extremities of diameter is given by $(x - x_{1}) (y - y_{1}) + (x - x_{2}) (y - y_{2}) = 0$

Answer»

which one of the following statements are correct?
1) Equation of a circle with centre $(h, k)$ and radius r is given by $(x - h)^{2} + (y - k)^{2} = r^{2}$
2) Equation of circle with $A (x_{1}, y_{1})$ and $B (x_{2}, y_{2})$ as extremities of diameter is given by

$(x - x_{1}) (y - y_{1}) + (x - x_{2}) (y - y_{2}) = 0$
