Given:
The equation of circle is

To find:
The polar form of given circle.
Solution:
We have,

![[\because (a+b)^2=a^2+2ab+b^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a%2Bb%29%5E2%3Da%5E2%2B2ab%2Bb%5E2%5D)

Subtracting 9 from both sides, we get

We know that,
and
.


and 
We know that, r is radius it cannot be 0. So,


Therefore, the correct option is A.
