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.
Help in what ? I cant see the photo
3.00 is 166.6% of 1.80 dollars
I can't really help without the amounts being given but I can say that two supplementary angles add up to 180 degrees, so I hope that helps
