Determine the center and the radius of the following circle:
x^2+y^2+6x4y5=0
I got for the radius 3(sqrt2)
I got for the center (3,2)
Can you please tell me if I am correct?
The radius seems wierd.

The answers are correct.
The radius is sqrt(18) which you have correctly reduced to 3sqrt(2), well done!
