Pizza eaters. Which is the better deal?

Price for one 20" pizza is $15. Price for three 10" pizzas is $15. Which is the better deal?Pizza eaters. Which is the better deal?
Now for the geek answer...



The area of a pizza (given it's round) is:



Pi * Radius^2



The radius of a 20" Pizza is 10", and for the 10" pizza it's 5".



10^2 = 100 per pizza

5^2 = 25 per pizza



Since Pi is a contant, it really doesn't matter for this question.



Three 10" pizza gives an area of 25*3 or 75, which is still less than 100.



You may end up with more "end pieces" with the three 10" pizzas...



Here endeth the lesson. :)
That totally just depends on how many people. If it is just a couple of people, I would just get the one 20 inch for 15. But if there are many people, who have different tastes, then the other deal is better.Pizza eaters. Which is the better deal?
The three 10'' pizzas will give you more pizza for your buck. However, I would say:



If you're more of a crust person, go with the three 10'' pizzas.



If you're more into the toppings, go with the single 20''.
the 3 10" is more dough most likely and you can get a variety of toppings on the 3. the one will also have larger pieces and might be harder to eat unless its a rectangle
bigger pizza... duh!
cell-hell answered the question, just not directly.



One 20" pizza has 33% more area than three 10" pizzas. If the pizzas have the same thickness, it also has 33% more volume. It is a better deal.



The 20" pizza has the added benefit of having 33% less edge distance than the three 10" pizzas, so it will probably have more toppings.
I say the three 10'' pizzas for 15 dollars
3 10" pizzas is a better deal.
Clearly the 3 for $15 is the better value.....you get 10 more inches of pizza for the SAME price!!!
