Example 3 Find the radius of the circle in which a central angle of 60Ā° intercepts an arc of length 37.4 cm (use Ļ€ = 22/7 ) Given š‘™ = 37.4 cm and Īø = 60Ā° Converting angle into radians We know that Radian measure = š…/šŸšŸ–šŸŽ Ɨ Degree measure = šœ‹/180 Ɨ 60 = š…/šŸ‘ radian Now, Īø "= " š‘™/š‘Ÿ " " š’“ = š’/šœ½ = (šŸ‘šŸ•. šŸ’)/(š…/šŸ‘) = (37. 4)/(22/(7 Ɨ 3)) = 35.7 cm
