18 Inch Pizza Bigger Than 2 12 Inch
When it comes to ordering pizza, size matters. You want to make sure you get enough to feed everyone, but you also don't want to order too much and have leftovers for days. One debate that has been going on for years is whether it's better to order one large 18 inch pizza or two 12 inch pizzas. In this article, we'll break down the math and settle the debate once and for all.
Size Comparison
First, let's take a look at the size difference between an 18 inch pizza and a 12 inch pizza. The 18 inch pizza has a diameter of 18 inches, while the 12 inch pizza has a diameter of 12 inches. At first glance, it might seem like two 12 inch pizzas would be bigger than one 18 inch pizza. However, that's not necessarily the case.
Area Comparison
When you calculate the area of a pizza, you need to use the formula A=πr², where A is the area and r is the radius (which is half of the diameter). If we plug in the numbers for an 18 inch pizza, we get:
A = πr² = π(9²) = 254.47 square inches
For a 12 inch pizza, the calculation is:
A = πr² = π(6²) = 113.10 square inches
So, the total area of two 12 inch pizzas is:
A = 2(πr²) = 2(π(6²)) = 226.19 square inches
As you can see, the area of one 18 inch pizza is actually larger than the area of two 12 inch pizzas. This means that you'll get more pizza if you order the larger size.
Cost Comparison
Another factor to consider when deciding between an 18 inch pizza and two 12 inch pizzas is the cost. In general, larger pizzas are more cost-effective than smaller ones. Let's take a look at the numbers.
Assuming that a 12 inch pizza costs $10 and an 18 inch pizza costs $20, the total cost of two 12 inch pizzas would be:
$10 x 2 = $20
Meanwhile, the cost of one 18 inch pizza is also $20. So, in terms of cost, it's a wash.
Conclusion
So, what's the verdict? When it comes to ordering pizza, it's better to go with one large 18 inch pizza than two 12 inch pizzas. Not only will you get more pizza, but it's also more cost-effective. Of course, if everyone in your group has different preferences when it comes to toppings, it might make more sense to order multiple smaller pizzas. Ultimately, it's up to you to decide what works best for your situation.
