9 is more than 2 times 4

yeah, but
C_1 = pi * d = 3,14 * 18 = 56,52
C_2 = pi * d * 2 = 3,14 * 12 * 2 = 75,36

so the smaller ones have 50% more crust and are therefor more delicious.

fun fact: to find the actual diameter of the pizza that would larger by a factor of x its (D/2)*2√x

good luck finding a place that offers irrational size pizza though

But… it’s twice as many slices!

I found myself making a similar calculation recently - I have a project car, and when I dragged it out of a field and hacked the vegetation out of the engine compartment, there was a 40mm motorcycle carburetor mounted to an adapter mounted to the intake. The carburetor even had a Harley-Davidson logo embossed in it.

I wanted to put a two-barrel Weber carb on it, which had a 36 mm and a 32 mm throttle plate. The 40 mm motorcycle carb had an area of 1256 mm^2^, while the combined area for the Weber was more like 1820 mm^2^.

Is this a prank
