@median silo if you ask other ppl to do something for you you wont improve

For question 1 you complete the square and you can find the centre of circle when you do that

question 2 is the radius of the circle which can be found when you find the equation of the circle

(x+a)^2 + (y+b)^2= r^2

Third one is pythagoras

4th you sub y= x/2 -6 into the equation of the circle

5th you find the value

of y using the x coordinate you just found

True but my teacher isn’t answering me

Is it possible you can do a written solution so I can annotate it it’s cool if u can’t

[bleak moon]

not helping you any more @median silo

r^2=20 so r must be ...
