Transcript: Imagine a scenario… Ready to order? Yes, I would like to order a 9-inch pizza. I am sorry, the 9-inch pizza is not available. But, I will give two 5-inch pizzas instead. With 10 inches in total, you will get 1 inch more for free! Will you accept the offer? Probably… Who doesn’t love more pizza for free! But… is it actually a better deal? Well, let’s break out your calculator or your thinking brain with us. To find the area of the pizzas, we’ll use the equation A = πr², where r is the radius of the pizzas. Let’s figure out the area of two 5-inch pizzas! First, we will find the radius, which is 5 inches divided by 2, so 2.5. Then, square 2.5 and multiply it by 3.14, or π. It will give us 19.6 square inches. Now, because there are two pizzas, multiply that number by 2 for 39.2 square inches. Meaning two 5-inch pizzas gives us 39.2 square inches of pizza. Now, let’s figure out the area of one 9-inch pizza! First, we will find the radius, which is 9 inches divided by 2, so 4.5. Then, square 4.5 and multiply it by 3.14, or π, giving us 63.6 square inches. Meaning one 9-inch pizza gives us 63.6 square inches of pizza. Two 5-inch pizzas = 39.2 square inches… One 9-inch pizza = 63.6 square inches… Clearly, getting two 5-inch pizzas with the bang of 1 inch for free is not the better deal! Now you see how math is important in our everyday lives and for our belly! Next time you order a pizza, you can bring out your inner math self to calculate the best deal because every situation is different. Depending on the size difference, two smaller pizzas could be better than one large pizza! It all depends on the radius and the price! But! Of course, the calculations assume that the thickness of all pizzas is the same! Even if two smaller pizzas are better than one larger pizza, smaller pizzas might mean more crust and fewer toppings. Pros and cons… Oh, life is hard!
