30 lip 2024 · This arc length calculator is a tool that can calculate the length of an arc and the area of a circle sector. This article explains the arc length formula in detail and provides you with step-by-step instructions on how to find the arc length. You will also learn the equation for sector area.
The arc length is \(\frac{1}{4} \times \pi \times 8 = 2 \pi\). Rounded to 3 significant figures the arc length is 6.28cm. The formula to calculate the arc length is:
The arc length of a circle can be calculated with the radius and central angle using the arc length formula, Length of an Arc = θ × r, where θ is in radian. Length of an Arc = θ × (π/180) × r, where θ is in degree.
Learn how to calculate the arc length of a sector of a circle using the formula l = (θ/360) × 2πr, where θ is the angle of the sector in degrees and r is the radius of the circle. See examples, video lessons and practice questions on sectors of a circle.
