Formula for arc length
WebThe arc length is: L = θ × r (when θ is in radians) L = θ × π 180 × r (when θ is in degrees) Finding the Radius from Width and Height Say you know the width and height of an arc (maybe it is on the top of a door) and you … WebSolution: The radius of sector = r = 10 feet. Arc length = l = 12.56 feet. Area of the sector without an angle = l r 2 = 12.56 × 10 2 = 62.8 sq. feet. Perimeter of sector = 2 r + l = 2 ( 10) + 12.56 = 32.56 feet. Find the arc length of a sector having a radius of …
