I believe but that was quick mental math
Since the total circumference of the circle is 60 pi cm which passes around 360˚, the length of an arc of 140˚ will be equal to 140/360 = 7/18 times the total length:
l = (7/18) * 60 pi cm = 23.3 pi cm
Answer:
They are equalivalent. 4 is half of 4 which makes is equal to 1/2
