Center of the origin, √11

Question

I can't answer

 

Answer 1

You can't ASK, i.e., you have not stated clearly the given facts nor have you asked a question in English.

 

If you want the equation of a circle centered at (o,o) and having radius r =√11, that is the way to ask it.

It should be easy to state the answer, using basic facts in your textbook (or equivalent material):

x² + y² = 11
