The line that goes around, or envelopes, a circle is the circumference of the circle. It is found by multiplying the diameter of the circle, which is a line that crosses the center, by pi.
The diameter of a circle is a straight line going from one point on its boundary, through the centre of the circle, to the boundary on the other side.
Not at all! The circumference is the length of the boundary of a circle. A chord is a straight line(or a line segment) that passes through two points on the boundary of a circle (or on a curve).
its called a Radius
The radius of a circle is a line segment joining any point of the boundary of the circle to its centre. A diameter is a line segment from a point of the boundary of the circle which passes through the centre and ends at the boundary on the opposite side.

Do you mean, like, the Earth? The equator. If you mean the line going from side to side across the middle of a circle then... the diameter of a circle
It is an "open" circle. That is, a circle which is not filled in.
The only state with part of its boundary defined by the arc of a perfect circle is Wyoming. The eastern boundary of Wyoming follows the 42nd parallel north latitude line, which forms part of a perfect circle around the Earth.
A line that goes through a circle is a secant line. (Remember that a line is infinitely long.) Anyline that passes through a circle is a secant line, whether it passes through the center of the circle or not. Compare this to a line segment with endpoints on the circumference of a circle. That segment is called a cord of that circle. If the cord of a circle passes through the center of that circle, it is a diameter of that circle, which is the longest cord of the circle.

The radius of a circle is one half of the circle's diameter, any line going from the center of the circle to the circle itself. A line connecting other points on a circle (or on any curve) is called a chord.
