Auto insurance companies offer discounts if you are good student, or full time student (which includes your gpa).
grants and scholarships are rewarded by good grades and succession of essay writing.
students will get kicked off their athletic team if their GPA is too low.
That singles out comparing yourself to your friends, which should be obvious that this one's excluded. ☺
Answer:

Explanation:
We need to write the polar form of the given equation :

Put
and 
![x^2+(y-6)^2=36\\\\(r\cos\theta)^2+(r\sin\theta-6)^2=36\\\\r^2\cos^2\theta+r^2\sin^2\theta+36-12r\sin\theta=36\ \ [\because (a-b)^2=a^2+b^2-2ab]\\\\r^2(\cos^2\theta+\sin^2\theta)-12r\sin\theta=0\\\\\text{We know that}, \cos^2\theta+\sin^2\theta=1\\\\r^2-12r\sin\theta=1](https://tex.z-dn.net/?f=x%5E2%2B%28y-6%29%5E2%3D36%5C%5C%5C%5C%28r%5Ccos%5Ctheta%29%5E2%2B%28r%5Csin%5Ctheta-6%29%5E2%3D36%5C%5C%5C%5Cr%5E2%5Ccos%5E2%5Ctheta%2Br%5E2%5Csin%5E2%5Ctheta%2B36-12r%5Csin%5Ctheta%3D36%5C%20%5C%20%5B%5Cbecause%20%28a-b%29%5E2%3Da%5E2%2Bb%5E2-2ab%5D%5C%5C%5C%5Cr%5E2%28%5Ccos%5E2%5Ctheta%2B%5Csin%5E2%5Ctheta%29-12r%5Csin%5Ctheta%3D0%5C%5C%5C%5C%5Ctext%7BWe%20know%20that%7D%2C%20%5Ccos%5E2%5Ctheta%2B%5Csin%5E2%5Ctheta%3D1%5C%5C%5C%5Cr%5E2-12r%5Csin%5Ctheta%3D1)
Hence, the above is the polar form of the given equation i.e.
