WebJan 20, 2024 · The formula to calculate the length of the arc is given by: L = r θ. Where, L is the length of the arc. Given: r = 0.5m and θ = π/4 radians. Length of arc = 0.5 × π/4. Length of arc = 0.392 m (π = 3.1415) Thus, the length of the arc is 0.392 m. Example 5: Find the length of the arc with a radius of 10cm and an angle of 135°. Solution: WebThe arc length of a circle can be calculated using different formulas, based on the unit of the center angle of the arc.

WebSo when you add these two together, this arc length and this arc length, 0.5 plus 17.5, you get to 18 pi, which was the circumference, which makes complete sense because if you … WebThe formula for the length of a chord is: d = 2•r•sin (a/2r) where: d is the length of the chord. r is the radius of the circle. a is the arc length. The length of the chord (d) is the distance between two points on a circle. θ= a / r. sin (θ/2) = ½ d/r. WebApr 7, 2024 · Notice that this question is asking you to find the length of an arc, so you will have to use the Arc Length Formula to solve it! Before you can use the Arc Length Formula, you will have to find the value of θ (the central angle that intercepts arc KL) and the length of the radius of circle P..
