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
Diameter runs straight across. Radius only goes half way, to the center.
Line through the center of a circle is the diameter or distance across the circle.
If you draw a line from one side of a circle to the other, and that line hits the center, and goes all the way across, it is the diameter. half of that line going from the center to the edge of the circle is the radius.
A diameter goes all the way across a circle through the center. A radius goes half way across, from the center to any point on the circle. So a circle's diameter is two times its radius.All the way through the centre of the circle but the radius only goes half way from the centre 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.
Diameter, don't confuse it with the radius which is the line that goes from centre to rim.

diameterA straight line between one point on a circle's edge and another is called a chord. A chord that goes through the centre is called the diameter.The disance across a circle is called a diameter, if you half that it will be called the raidus
The distance half way across a circle is the circle's radius.radias
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.
It is a diameter, the line that cuts the circle in an exact half.It is the diameter and passes through the center of the circle.
Measure the diameter of the circle,this is a line taken right across the circle that goes through the centre. Now multiply by pi =3.142 and divide by 2 to get the length of half the circumference.
