+120 In the gym, there is a scale that measures people's weight. The needle is 22 cm long, and it rotated 124° when Evelyn stepped on it. How far did the needle travel as it rotated?
+426 Length of needle = Radius of Circle
= 22 cm
Circumference of circle = 2πr=2π×22(π=3.142)=2×3.142×22=6.284×22=138.248
The answer is rounded to 3 decimal places.
Answer: 47.619 cm
