Buying Pizza at Domino’s

…just had a most significant realization. It turns out that the L-sized pizza at Domino’s is actually bigger than what most people expect.

Here’s how it goes: the L-sized pizza is 36 cm in diameter, while the M-sized pizza is pegged at 25 cm.

Now we will compute the difference of the pizzas’ sizes. Since the breadth of both are the same, we quit talking “volume,” go ahead and talk “area” of each pizza’s cross-section.

Here goes:
.
Area of a circle(which is, or which almost is, a pizza cross-section’s shape):

A = PI x r²

where A (you guessed it right) is the area, r is the radius and PI is 3.14159…¹

So taking the “areas” of both the M- and L-sized pizzas (we name them A_M and A_L, respectively):

A_M = PI x (25 / 2)² = 491 cm²

A_L = PI x (36 / 2)² = 1018 cm²

Generously rounding off both to the nearest multiple of 500, we can say that a cross-sectional M-sized pizza’s area is 500 cm², while that of the L-sized pizza is 1000 cm², which is twice (or actually more than twice, pre-round off) that of M.

Recommendation: Rather than buying 2 M’s , just buy one L with the half-half² option (or better yet, the quadro³ option) and you get the same amount of bread at (give or take) 25% less.

1 Technically speaking, PI is the ratio of a circle’s circumference to its diameter. …Because PI is an irrational number, its decimal representation neither ends nor repeats. Another (although somewhat erroneous ) way of describing how it looks like: just think of millions of billions of numbers all jumbled up with no recognizable pattern whatsoever. …Daniel Tammet, an autistic savant, is the record holder for memorizing and recounting PI to an astounding 22,514 digits!!!

2 Through the half-half option, you can order a combination of 2 different halves for no additional charge .

3 You can get 4 different flavored quarters, all in one pizza. Last I checked though, rather than being able to handpick each quarter, it seems that you can only choose between “ready-made” quadro combinations.
