Answer:
18.18583 cm
Step-by-step explanation:
As per circle arc theorem we have
arc length s = Central angle* perimeter of the circle / 360
Here given that radius = 7.5 cm
Hence circumference = 2 (3.14)(7.5) = 47.1 cm
Central angle / 360 = 139/360 = 0.3861111
Hence arc length = 0.3861111*47.1 = 18.18583 cm
