WebCentral angle = 2 radians Step 1: Sector area = 25 ⇒ (1/2) r 2 (2) = 25 Step 2: This gives r 2 = 25. By taking square root on both sides, r = 5. Step 3: Arc length = rθ = 5 × 2 = 10 units Thus, arc length = 10 units Central angle and the chord length: The chord length formula is, 2r sin (θ/2). Use this formula and solve for the radius 'r'.
