Answer:
Arc length of the partial circle = 3π units
Step-by-step explanation:
Given question is incomplete; please find the complete question attached.
Formula for the arc length of a circle = 
Here θ is the angle formed by the sector at the center.
Angle that is formed at the center of the circle is = 360° - 90°
= 270°
So, length of the arc = 
= 3π
Therefore, length of the given partial circle is 3π units.
Y=180-111=69
x=360-123-70-69=98
That's your answer.
