Corbett maths sector area and arc length
WebSo in the below diagram, s = r∅ . Area of Sector The area of a sector of a circle is ½ r² ∅, where r is the radius and ∅ the angle in radians subtended by the arc at the centre of the circle. So in the below diagram, the … WebA circle has an angle of 2 π and an Area of: πr2. A Sector has an angle of θ instead of 2 π so its Area is : θ 2π × πr2. Which can be simplified to: θ 2 × r2. Area of Sector = θ 2 × r 2 (when θ is in radians) Area of Sector = θ × π 360 × r 2 (when θ is in degrees)

You already know that the radius r is equal to 5. But what about θ ? ∠AKB and ∠AKC are supplementary
WebSolution: Use this formula: length of a sector = ( θ 180)πr = ( θ 180) π r length of a sector = ( θ 180)πr = ( θ 180) π r = ( 60 180)π(24) = (1 3)π(24) = 8 ×3.14 ≅ 25.1 = ( 60 180) π ( 24) = ( 1 3) π ( 24) = 8 × 3.14 ≅ 25.1 cm c m Arc Length and Sector Area – Example 2: WebCreated Date: 20241021104556Z'
WebIf you know the arc length and the radius, then the angle that is subtended by the sector is θ = L / r where L= arc length and r = radius (Angle in radians, of course.) Thus, the area of the sector would be: A = (θ / 2π) (π r²) A = ½ θ r² Now, we plug in the formula for θ A = ½ (L/r) r² A = ½ r L 1 comment ( 4 votes) Upvote Downvote Flag more
