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.
Sounds like a roundabout, where some roads meet and you have to drive round the middle... Do you know what a Polo Mint looks like?

If you mean a circle, use the formula area = pi x radius2. Approximating pi by 3.14 should be close enough for most purposes.
The RADIUS. Other nomenclature for a circle are:- Diameter ; Two radii forming a straight line through the circle centre. Chord ; A straight line from one point on the circle to another point on the circle that does NOT pass through the circle centre. Arc ; Part of the circumference. Segment ; An area inside the circle bounded by two radii and an arc. Tangent ' A line just touching the circle's circumference in ONE place. NB The plural of the noun 'Radius' is 'RADII' , not radiuses. 'Radii' is pronounced 'Ray- dee - eye'. NNB 'pi' is the Classical Greek small case letter 'p' , for 'proportion. It is an Irrational number, but for elementary(school) purposes it is given as the approximation '3.14' or '22/7' Being an Irrational number means the decimals are NOT in any regular order and go to infinity. pi ~ 3.141592.....
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!
The Circle is the Interstate Highway intersection of 90, 94, and 290 which is a major traffic bottleneck.

No, but pollution is affecting the stone in it. It sits in the middle of a traffic circle.

The word roundabout dates from the early 20th century, In the U.S., the term traffic circle is used where entering traffic is either controlled by stop signs, traffic signals, or is not formally controlled at all, while roundabout is reserved for circles where entering traffic must yield to traffic already in the circle.Yes, yes, but who invented it ?
