WebFeb 9, 2024 · The arc length formula is used to find the length of an arc of a circle; ℓ = θr ℓ = θ r, where θ θ is in radian. The circle’s circumference is C = 2πr C = 2 π r, as the centre angle is 2π 2 π. Correspondingly, when the centre angle is θ θ, the arc, which is a part of the circumference, is calculated as; ℓ = 2π × θ 2πr = θr ℓ = 2 π × θ 2 π r = θ r 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
WebFind the area and perimeter of a sector with a radius of 10 feet and an arc length of 12.56 feet. Solution: 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.
