Answer:
AHH! Geometry!
14.1375
Step-by-step explanation:
So to get the answer, we are going to have to make a "factor"
We first do this:(Circles have an angle of 360)
[tex]\frac{90}{360} =\frac{1}{4}[/tex]
This tells how long the arc is in comparison to the circumference!
So let's solve the circumference!
[tex]P=D\pi \\P=18\pi \\P=About 56.55[/tex]
Now, Multiply!
[tex]56.55*\frac{1}{4} = 14.1375[/tex]
There we go!
Hope this helps!
See Ya!
