Answer 1

@Zarkon @mathmath333 Someone????

Answer 2

I think is Exterior but I don't know if i'm right??

Answer 3

(x + 2)2 + (y - 3)2 = 81?

P(8, 4) So would this be exterior?

Answer 4

yes

Answer 5

Thank you

Answer 6

yw

Answer 7

you can also find distance by the formula
\[d=\sqrt{\left( x -h \right)^2+\left( y-k \right)^2}\]
where (h,k) is the center and (x,y) is the point
if d<r then the point lies within the circle.
if d=r,then point lies on the circumference,
if d>r then the point lies outside the circle.
