Answer:
8 glasses
Step-by-step explanation:
Total volume : 1500 ml
Glasses capacity : 180 ml
Glasses can be filled : 1500 / 180 = 8.33
Notice it says completely fill thus it is 8 glasses
28/x = 40/100
Cross multiply
40x = 28(100)
40x = 2800
Divide both sides by 40
x = 70 students
12.9
Diameter is just the radius times 2
