Best ResponseYou've already chosen the best response.0i think its the last one r^2=64 r=8

Best ResponseYou've already chosen the best response.1no but when you are converting to a polar equation \[r=\sqrt{x^2+y^2}\]

Best ResponseYou've already chosen the best response.1therefore \[r^2=x^2+y^2\]

Best ResponseYou've already chosen the best response.1so you are replacing the \[x^2+y^2 \]

Best ResponseYou've already chosen the best response.1but if you teacher wants r itself then r is \[r=2\sqrt{2}\]

Best ResponseYou've already chosen the best response.1r cant be 4 because you have are taking the root of 8 not halving it
