Arc Length

Arc Length (arc length) is a circles relationship written as Arc = (angle/360) × circumference or L = (θ/360) × 2πr. Students use it to solve unknowns when enough values are known.

Write Arc = (angle/360) × circumference, substitute the known numbers carefully, then simplify. Worked walkthrough: θ = 90° r = 7 L ≈ (90/360)×43.96 ≈ 10.99.

Arc Length usually appears in circles units during middle or secondary school. Match difficulty with MathDigits grade worksheets so practice fits the curriculum year.
