The general equation for a circle is:
Where (a,b) is the centre of the circle and r is the radius.

so I got the answer:
It counted it incorrect, what did I do wrong?
You're almost there! I get a different constant (ie not -109).
Im confused...cause aren't you supposed to subtract the 125 from -16?
or I must be adding or subtracting something wrong right...
I got -125?
does that sound better?
