Answer:
[tex]x^{2} +y^{2}=r^{2}[/tex]
Step-by-step explanation:
We know that the center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r".
As given the center of circle q is origin ie,(0,0);
Now substitute the point P in the equation of the circle as it lies on it.
