Answer:

Step-by-step explanation:
Recall that the equation of a circle of radius R centered at
is given by:

For your particular case: R = 6,
= 2, and
= -5, therefore the equation becomes:

13=3+10
so it is now
3+10-7
we know that 10-7=3 so we now have
3+3=6
tada
yea just put a line over the 0 to indicate it's infinite
