WebSep 3, 2024 · 1. I think there's no elementary formula for this. Denote arc and chord as a, b, then r θ = a, 2 r sin ( θ / 2) = b. Divide the first equation by the second, we get. θ 2 sin ( θ / 2) = a b θ = 2 a b sin ( θ / 2). Subsitute θ / 2 with u, we get. u = a b sin u. which is an equation you can't give simple solution to.

WebThat's what we're going to try to solve for. We know that the central angle is 10 degrees. So you have 10 degrees over 360 degrees. So we could simplify this by multiplying both sides by 18 pi. And we get that our arc length is equal to-- well, 10/360 is the same thing as 1/36. So it's equal to 1/36 times 18 pi, so it's 18 pi over 36, which is ... orchids decor ideasWebMar 29, 2024 · Solving When the Central Angle is in Radians. 1. Set up the formula for arc length.
