You will need 119 cups to sell all of the lemonade.
Step-by-step explanation:
Given,
Diameter of cups = 9 cm
Radius of cup =
Height of cups = 12 cm
We will find volume of cup.
Putting all the values
Therefore;
Each cup can hold 254.34 cubed centimeter of lemonade.
Number of gallons = 8
1 gallon = 3785 cm³
8 gallons = 3785*8 = 30280 cm³
Let,
x = Number of cups
Volume of lemonade in one cup * Number of cups = Volume of 8 gallons
254.34x=30280
Dividing both sides by 254.34
Rounding off to nearest whole number
x = 119
You will need 119 cups to sell all of the lemonade.

Hence, the number is an element of either the set of rational numbers or the set of irrational numbers.
Option (A) is the correct option.
