Find arc length of a sector
WebJul 3, 2024 · The formula for finding a sector angle is: Sector Angle = Arc Length * 360 degrees / 2π * Radius The 360 represents the 360 degrees in a circle. Using the arc length of 3 inches from the previous slide, and a radius of 4.5 inches from slide No. 2, you would have: Sector Angle = 3 inches x 360 degrees / 2 (3.14) * 4.5 inches WebThe following is the calculation formula for the arc length of a sector: Where: A = arc length of a sector π = 3.141592654 r = radius of the circle θ = central angle in degrees …
