The volume of the pizza (assuming same thickness of the crust and circular shape) is pi*r^2*thickness, where r is the radius of the pizza.
In this case, the ratio of the volumes is roughly proportional to the ratio of the amounts of flour used. Therefore the ratio of volumes is 4.5/3 = 1.5.
The ratio of the size of the pizzas (radius) = sqrt(1.5).
