WebHOW TO FIND RADIUS WHEN ARC LENGTH IS GIVEN Example 1 : The arc length of a sector is 66 cm and the central angle is 3 0°. Find its radius. Solution : Arc length of a sector = 66 cm Central angle = 3 0° = (θ/360) ⋅ 2Πr 66 = (30/360) ⋅ 2 ⋅ (22/7) ⋅ r (66 ⋅ 7 ⋅ 360) / (30 ⋅ 22 ⋅ 2) = r r = 126 cm So, the radius of the sector is 126 cm.
