No, the cord of a circle does not have to go through the center of that circle. A chord that does go through the center of a circle is a special case and is called the diameter. A chord can connect any two points on a circle.

What is a segment whose endpoints are on a circle?

A chord. a diameter also has endpoints on a circle, the only difference is a diameter goes through the center point and a chord doesnt have to go through the center. a diameter is considered a chord.


How many feet go around a 20 ft circle?

The circumference of a circle can be calculated using the formula C = 2πr, where C is the circumference, π is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. In this case, the radius is half of the diameter, so for a 20 ft circle, the radius would be 10 ft. Plugging this value into the formula, we get C = 2 x 3.14159 x 10 = 62.8318 ft. Therefore, approximately 62.83 feet would go around a 20 ft circle.


What is the best estimate of the circumference of a circle 2 units?

The Circumference of a circle (C) equals the number "pi" times the diameter of the circle (d). "pi" (3.14159...) is a number which you can never find the value of precisely, the numbers after the decimal point go on for ever. Given this information you can calculate what you need to know about your circle.


What is the formula for sine?

Sin, Cos and Tan is the formula for sine. A right-angled triangle is a triangle in which one of the angles is a right-angle. The hypotenuse of a right angled triangle is the longest side, which is the one opposite the right angle. The adjacent side is the side which is between the angle in question and the right angle.

What is a segment that has both endpoints on the circle called?

It's called a "chord" of the circle. If it happens to go through the center of the circle,then it's also called a "diameter" of the circle, and no other chord in the same circlecan be longer.


How is a diameter a chord and a chord not a diameter?

Every chord is a line on the inside between two points on the circle. A diameter does that, so it's a chord. But in order to be a diameter, a chord also has to meet another requirement ... it has to go through the center of the circle. A lot of chords don't do that, so they can't be diameters.


What name is given to a line segment with endpoints on the circle?

The name is "chord".If the line segment happens to go through the center of the circle, thenit is also given the additional name "diameter", and no other chord in thesame circle can be longer than that one is.


What is a line through a circle that does not go through the center?

A line through a circle that does not go through the center of the circle is a secant line. A line through a circle that does go through the center is still a secant line, by the way. Compare this to a line segment that has its two endpoints on the circumference of the circle. That line segment is a cord of the circle. If that cord of the circle passes through the center of the circle, then the cord is a diameter of that circle.


Is a chord or a diamater longer?

In a circle, there are 1 or more chords, and only always 1 diameter. The diameter goes through the middle point in a circle and connects 2 points on a circle. A chord does not have to go through the middle, but can. The diameter always counts as a chord. So, either, both the chord and diameter are the same length, or the chord is shorter. I hope this answers your question! (:


Do all chords go through the origin of a circle?

No. The only chords that go through the center is a diameter.


How do you divide a circle into three parts?

I assume that you want to divide it into three equal "pie slices".If you have the location of the center of the circle, and are allowed to use a protractor (or other angle-measuring device), then you draw a radial line segment from the center to the circle, then another radial line segment at a 120° and to the first radial line segment, and final radial line segment at a further 120° angle.If you have only the circle, a straight-edge, and a compass, then you must first locate the center of the circle. Draw two cords, Use the compass to construct bisecting perpendicular lines for each chord. These bisecting perpendicular lines will meet at the center of the circle.If you now draw a chord equal in length to the radius, and radial lines from each of its ends, then that gives you a "pie slice" that is one sixth of the circle! So if you draw a second chord where the first ends, you have a "pie slice" that is one third of the circle.So you could draw five chord, each the length of the radius, each starting where the previous ended, and draw radial lines through every second chord-end. Or you could use the first two chords to find the length of a chord which corresponded to a third of the circle.(Actually, you don't really have to draw any of these chords, you just need to mark their end-points as you go along.)


Does a diameter go all the way across or halfway across a circle?

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


Does always a tangent to a circle pass through the center of the circle?

the tangent will never go through the center of a cirlce. The tangent is, by definition, a line that only intersects the circle at one point. If you look down a pencil along its long axis, so that it appears to be a circle, and place your finger on top of and perpendicular to the pencil, your finger is now tangent to the circle you see.


How do you find radius if you know the chord?

well,first the radius is half of the chord. Radius is the distance from the circle centre to the chord end. The chord is the line joining the ends of the arc. Draw this line. Call the distance from the arc of the circle at its deepest point to the mid point of the chord "c". If extended, this line will go throught the centre of the circle. Call half the length of the chord "y". Then the properties of circles and chords is that c(d-c)=y2 where d is the circle diameter, so that d = y2/c + c. And then radius is half that.


How do you get the formula center of curvature?

This starts with the collocation circle to go through the three points on the curve. First write the equation of a circle. Then write three equations that force the collocation circle to go through the three points on the curve. Last, solve the equations for a, b, and r.
