Answer:

9.423

Step-by-step explanation:

Using 3.141 as Pi

Using the Arc length equation:

Arc length = [tex]\pi d * angle/360[/tex]

As the angle of the missing section is 90 degrees, and all angles around a point must be 360 degrees, it leaves 360-90 = 270 degrees for the angle.

As the radius is 2, the diameter is twice the length of the radius so 2*2 = 4 so the diameter is 4.

[tex]\pi 4 * 270/360[/tex]

3.141 * 4 = 12.564

270/360 = 0.75

12.564 * 0.75 = 9.423

So 9.423 is the arc length.
