Answer:
128 servings
Step-by-step explanation:
5/4 cups of milk for 10 servings is equal to 1/8 cup per 1 serving
there are 16 cups in a gallon
let 'n' = # servings in a gallon
so 1/8 : 1 is 16 : n
1/8n = 16
n = 16(8)
n = 128
73/3.14=23.2484076433
Divide the circumference by π, or 3.14 for an estimation.
And that's it; you have the circle's diameter
