First, is it two 10-inch pizzas for $13.00 TOTAL, or $13.00 EACH? Once you know that, divide the total price of a pizza (or pizzas) by the total inches for price per inch...whichever number is lowest is the better deal.
If you tell me whether the 13 is total or per each pizza, I'd be happy to walk you through the math if you'd like. :)

Hi
Area(circle) =
Area[d=16" r = 8"] = 64pi in^2
Area[d=10" r = 5"] = 25pi in^2, two of them 50pi in^2
the 16" the better buy
