How to work out the angle of a sector formula
Web3 jul. 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 Sector Angle = 960 ...
