Sector arc length
WebThe length of an arc is just a length, so its units will be the same as for length (cm, m, etc) Worked Example AOB is a sector of a circle with angle 42°, as shown. The area of the sector AOB is 28 cm 2. (a) Find the radius of the circle, giving your answer correct to 2 … WebUsing the formula. L = 2 π r × θ 360. where L is arc length, you can rearrange to give: r = L 2 π × 360 θ. You know that L = 15 and that θ = 27, so put these values into the formula to obtain: r = 15 2 π × 360 27 = 31.83 c m. If you find this formula confusing I would think about it like this. The circumference of a whole circle is π ...
