@Shadow center:2,6 , radius: 64?

Answer 2

hmm

Answer 3

No

Answer 4

You got the center right, but not the radius

Answer 5

\[(x - h)^2 + (y - k)^2 = r^2\]
Do you see where you went wrong?

Answer 6

\[r^2 = 8 \rightarrow r = \sqrt 8 \rightarrow r = 2 \sqrt 2\]

Answer 7

@Shadow radius: \[2\sqrt{2}\]

Answer 8

Yes
