Answer:
11.81pi
Step-by-step explanation:
r^2=25pi
r=8.86
length=2pi(8.86)(240/360)
=17.72pi(2/3)
=11.81pi
The inequality can be:

Now you divide both sides by 150 to get the #of boxes.

Lastly, x is 20. So the maximum amount of boxes that the freight elevator can hold is 20
1.875 ounces for each student
