How do you find the measure of an arc knowing only the chord of arc and radius?
you have a triangle formed by the radius on 2 and the chord on the other. the angle in that triangle that is opposite the chord, find its measure in radians take that measure (in radians) and multiply it by the radius to get the arc length
What is the Formula for calculating chord length?
Assume you mean the chord of a circle? If the angle between the two radii from the ends of the chord is A, and the radius of the circle is R, the chord length L will be L = 2RsinA/2. You can prove this easily by joining the point bisecting the chord to the centre, you then have two rightangled triangles, with an included angle of A/2, and an opposite side of L/2. So sinA/2 = L/2R.
If a circle has a diameter of 15 inches can it also have a chord of 20 inches and how?
No. A chord is a straight line drawn between any two points on the circumference of a circle. The longest chord is when the points are on opposite sides of the centre of the circle (and passes through the centre of the circle). The straight line which joins the points on opposite sides of the centre (through the centre) is called the diameter of the circle. Therefore the longest chord possible is the diameter of the circle. A circle with a diameter of 15 in can have a chord with a maximum length of 15 in.
When is a Chord a diameter?
The longest chord of a circle is its diameter
In a circle whose diameter is 20in and a chord is 6in from the center what is the length of the chord?
the chord is 4in long
