Finding chord length by known arc length and radius Arc length 500 x width 250 x thickness 150 mm, outer radius 30 m to calculate chord length
friend:
Please explain the meaning of "arc length 500X width 250x thickness 150mm"!
Given the chord length of 25, the radius of the arc is 54, find the length of the arc
Can I use a calculator? Not if I don't
The chord length is 25 and the radius is 54. Making the vertical line of the string through the center of the circle, the angle of the center of the circle opposite to half of the arc can be calculated
The angle = sin ^ - 1 (12.5 / 54) * 2 = 27.5784 ° * 2 = 55.1535 ° (calculator)
Arc length = π R * 55.1535 ° / 180 ° = π * 54 * 55.1535 ° / 180 ° = 51.978 ≈ 52cm
Given that the chord length is 25 and the radius of the arc is 54, find the length of the arc
Center angle = 2 * arc sin ((25 / 2) / 54) = 2 * arc sin (12.5 / 54) = 2 * 13.3843 = 26.7686
Arc length = center angle * pi * 54 / 180 = 25.2288
Given that the radius R is 23.7 meters and the chord length is 10 meters, how to find the length of the arc? Please give me your advice
Let the center of the circle be point O, the intersection point of chord and circle is a and B, do OC perpendicular to the chord, get Ao = 5, sincoa = 5 / 23.7, look up the table and get arcsin (5 / 23.7) = (the degree of angle, you can check it yourself) and the angle AOB = 2arcsin (5 / 23.7), then the length of the arc = 2 * pi * r * 2arcsin (5 / 23.7) / 360
