Well firstly we need to find the distance between these two. This is the radius. This turns out to be 12u because there is 12 x wise between them. Now that this is is established finding the area and circumfrence are pieces ok cake. The formula for area is \(Pi R^2 \)And the formula for Circuference is 2PiR. So the answers when you plug in the radius are:

Area= 144Pi \(u^2\)(Units squared)

Circumference: 24Pi u

Hope this helps.
