The boundary line that goes around a circle is called the circumference. It is the distance around the circle and can be calculated using the formula (C = 2\pi r), where (C) is the circumference and (r) is the radius. The circumference is a fundamental aspect of circle geometry, reflecting the relationship between the circle's radius and its total perimeter.

What is the line that goes across a circle?
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.
What is diameter of a circle?
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.
Is circumference a chord?
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).
What is a line segment from the center of a circle to any point on the boundary of circle?
its called a Radius
What is the radius and diameter of a circle?
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.
What is the line that goes across a circle?
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.

What is the line that goes around the globe with a parallel line?
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
What is the type of circle used on a number line when the boundary point is not part of the solution set?
It is an "open" circle. That is, a circle which is not filled in.
What is the only state where part of its boundary is the arc o a perfect circle?
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.
Is A closed circle on the number line indicates that the boundary point is included in the solution set?
Yes, a closed circle on the number line indicates that the boundary point is included in the solution set. This means that the value represented by the closed circle is part of the solution to the inequality. In contrast, an open circle would signify that the boundary point is not included in the solution set.
What is a line that goes through a circle?
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.
What is a line that goes through a circle from top to bottom?
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 chord of that circle. If the chord of a circle passes through the center of that circle, it is a diameter of that circle, which is the longest chord of the circle.
