WebNov 16, 2024 · Thinking of the arc length formula as a single integral with different ways to define \(ds\) will be convenient when we run across arc lengths in future sections. Also, this \(ds\) notation will be a nice notation for the next section as well. Now that we’ve derived the arc length formula let’s work some examples. WebArc length = θ 360 × π × d= 360θ × π × d. θ – angle of the sector. dd – diameter of the circle. Or. Arc length = θ 360 × 2 × π × r= 360θ × 2 × π × r. θ – angle of the sector. rr– radius of the circle. In order to solve problems involving the arc length you should follow the below steps: Find the length of the radius ...
