You're planning on making 4 meatloafs for a party. You go to the store to buy breadcrumbs, and see they are sold by the canister. How many canisters do you need to buy?

•How much breadcrumbs does the recipe call for? It calls for 1 1/4 cups of breadcrumbs.
• How many meatloafs does the recipe make? It makes 1 meatloaf.
• How many servings does that recipe make? It says it serves 10.
• How big is the canister? It is cylindrical, 3.5 inches across and 7 inches tall.
• What is the net weight of the contents of 1 canister? 15 ounces.
• How much does a canister cost? $2.69
• How much does a cup of breadcrumbs weigh? I'm not sure, but maybe something from the nutritional label will help.

the volume of the canister is

pi r^2 h
= pi * 1.75^2 * 7 = 67.35 in^3
the volume of a cup is 14.44 in^3
so
the canister contains
67.35/14.44 = 4.66 cups

so a cup of crumbs weighs 15/4.66 = 3.2 ounces

To determine how many canisters of breadcrumbs you need to buy, you'll need to calculate how many cups of breadcrumbs are in each canister and compare it to the amount required by the recipe.

Let's start by finding out how many cups of breadcrumbs are in one canister.

Since the net weight of the contents of one canister is given as 15 ounces, we can look for information about the weight of one cup of breadcrumbs from the nutritional label or package instructions.

Once we have the weight of one cup of breadcrumbs, we can divide the net weight of the canister by the weight of one cup of breadcrumbs to find out how many cups are in one canister.

Now, with the information that the recipe calls for 1 1/4 cups of breadcrumbs and makes 1 meatloaf, we can calculate how many cups of breadcrumbs you need in total for 4 meatloafs.

Multiply the number of cups required for each meatloaf by the number of meatloafs you want to make.

Finally, divide the total number of cups required for 4 meatloafs by the number of cups in each canister to determine how many canisters you need to buy.

Keep in mind the cost of each canister as well to determine how much you will need to spend on breadcrumbs for your party.

To determine how many canisters of breadcrumbs you need, we need to calculate how many cups of breadcrumbs are in one canister.

1. Convert the dimensions of the canister into volume:
- The canister is cylindrical, with a diameter of 3.5 inches and a height of 7 inches.
- Using the formula for the volume of a cylinder (V = πr^2h), where r is the radius and h is the height:
- Convert the diameter (3.5 inches) to radius by dividing by 2: 3.5 / 2 = 1.75 inches
- Calculate the volume: V = π(1.75^2)(7) = 67.46 cubic inches
- The volume of the canister is 67.46 cubic inches.

2. Convert the volume of the canister to cups:
- Since 1 cup is approximately 14.4375 cubic inches, divide the volume of the canister by 14.4375 to get the number of cups:
- 67.46 cubic inches / 14.4375 cubic inches = 4.67 cups (rounded to two decimal places)
- The canister holds approximately 4.67 cups of breadcrumbs.

3. Determine how many canisters you need:
- The recipe calls for 1 1/4 cups of breadcrumbs to make 1 meatloaf.
- Since you're making 4 meatloafs for the party, multiply the amount of breadcrumbs needed for one meatloaf by 4: 1.25 cups x 4 = 5 cups.
- Divide the total amount of breadcrumbs needed (5 cups) by the number of cups in one canister (4.67 cups) to find out how many canisters you need:
- 5 cups / 4.67 cups = 1.07 canisters (rounded to two decimal places)
- You would need to buy approximately 1.07 canisters of breadcrumbs.

Since you can't buy a fraction of a canister, you would need to purchase 2 canisters of breadcrumbs to have enough for 4 meatloafs for your party.
