Well, the circumference of a circle is its diameter x pi (for the purposes of this, we will consider pi to be 3.1415) so that the circumference can be expressed as 4pi or as 12.566.
A big circle with nothing in it on a traffic sign typically indicates a regulatory prohibition or restriction, often signaling that a particular action is not allowed. This blank circle can represent a "no entry" sign or the absence of a specific directive, depending on its context. Drivers should interpret it as a warning to proceed with caution and be aware of any regulations in the area.

If you mean a circle, use the formula area = pi x radius2. Approximating pi by 3.14 should be close enough for most purposes.
A traffic circle is un rond-point.
Follow the road laws of the country that you are in. In some countries the traffic already in the circle has priority. In others, traffic entering the circle has priority. Very clearly a recipe for disaster if you forget which country with which rules you are in!
