Answer 1

\[4(\sqrt{3}\]

Answer 2

what is \(4 \sqrt 3\)? circumference?

Answer 3

pi

Answer 4

pi?

Answer 5

\[4(\sqrt{3}\pi)\]

Answer 6

that's circumference?

Answer 7

So its the same?

Answer 8

what?? im asking if that's circumference

Answer 9

yes

Answer 10

\[C = 2\pi r = 4\sqrt 3 \pi\] therefore \[r = \frac{4\sqrt 3 \pi}{2\pi}\] tell me what you get

Answer 11

\[2\sqrt{3}\pi)\]

Answer 12

good...now you can solve for area \[A = \pi r^2\]
