Did math on Pizza hut’s Pizza to check how much is it covered with the toppings.

R= Radius of pizza
r= Radius of portion covered with topping

R=13cm
r=10cm

A=Total area of Pizza
a=Total area of Pizza covered with toppings

A= π R² = 530.93 cm²
a= π r² = 314.16 cm²

Area not Covered with Toppings = A-a = 216.77 cm²

Percentage of Area not Covered with Topping >

= (216.77/530.93) x 100 = 40.82

Roughly 41 % of pizza is not covered with topping.

There is no issue here. it is just to illustrate how drastically these numbers change and how what look like 80-90% covered is actually only 60% is covered with toppings.

Same can be seen in Dominos. They reduced there size. If they went from 13cm to 10cm. To us It will look like they just reduced 3 cm but in actual 41% pizza is gone.

    @MathNerd - is this correct?

    Also OP - you can cut and paste this into your post:
    R²

    What if you order a Stuffed Crust with little extra? Will that fix your maths issue?

    I seriously think OP is hungry for pizza, doesn't matter where you buy your pizza it's comes with a crust.

    • Kosmo-Kramer on 10/01/2024 - 00:05

      I was just having it :) and got curious when i saw crust coz this time it was felt they reduced the toppings so i did the math. I still prefer pizzahut coz dominos just shrunk their pizza. And they had one that i really liked “Spicy Veg Trio” for 5$ but they removed it last year or in 22 i think. Use to buy it, swirl of Heinz Peri Peri and it tasted so delicious.

      • boomramada on 10/01/2024 - 11:42

        You have to understand, that everything has gone up in price lately yet Pizza is still the cheapest fast food and crust has always been there.
        Yeah of course Pizza Hut is better than Domino but generally cheaper. I remember back in the days when Pizza Hut all you can eat dine-in, we didn't eat the crust lol

        • ATTS on 11/01/2024 - 19:41

          Lol nice

          Just curious did the staff get icky when they saw a pile crust on the plates afterwards

    Ahaha, great thread.

    Did math

    Pizzas are 3-D

    Same can be seen in Dominos. They reduced there size.

    Can confirm our pizza sizes at Domino’s have not changed.

      lol when are you comparing to, they've definitely reduced in size over the years!!

      We're not idiots. That might be the official line but they've decreased significantly in size. They're literally half the size of local pizzeria around the corner and even with a 50% off voucher they're only 10% cheaper. It's a joke that you can fit a whole "large" pizza on a side plate.

      • Puglife on 10/01/2024 - 08:20

        Exactly, a local pizzeria "large" pizza I would struggle to eat on my own.
        A dominos pizza I eat the whole thing and then I am in my pantry looking for food to fill me up. And FYI I'm not a big guy or a big eater!

      They've reduced it at least twice over the years
      Source: I worked there too long

      Check your facts before posting, especially if you claim to be an employee

        Pizza size hasn’t changed in my time (post 2017).

    • Jugganautx on 11/01/2024 - 17:49

      The $3 extra large pizza is the new large.

  • altomic on 10/01/2024 - 01:49

    similar theme with in-depth math analysis of domino's pizza from 5 years ago

    including discussion of Crustage (C) i.e. the "naked/nonsauce" area and then the Topping Area (TA)

    back then the size of regular pizza was stated to have a diameter of 28cm - according to domino's.

    I had domino's tonight and the diameter was ~ 27.5cm (just measured the cold left over pizza in the fridge - does pizza shrink when it is refrigerated?)

    the size 5 years ago might have been rounded up or even exaggerated ¯_(ツ)_/¯

    so pretty similar size from 5 years ago to today

      Topping Area (TA)

      Why not toppage?

    You are correct! The percentage of pizza not covered with toppings is roughly 41%. It’s interesting how the numbers can be deceiving, and what looks like 80-90% covered is actually only 60% covered with toppings. This phenomenon is not unique to Pizza Hut, as you mentioned. In fact, Dominos has also reduced their pizza size from 13cm to 10cm, which makes it look like they only reduced 3cm, but in reality, 41% of the pizza is gone (https://www.ozbargain.com.au/node/825380).

    I hope this information was helpful. Let me know if you have any other questions!

    Did math

    So that’s the story in the US.
    What happens when you do the maths on an Australian pizza?

  • Neoika on 10/01/2024 - 08:38

    Another math to verify in the Domino's marketing email: "Extra Large Pizzas are 50% bigger in surface size post-bake, and have 50% more toppings, than Large Pizzas."

  • pegaxs on 10/01/2024 - 09:45

    What is doing my head in is that a 26cm diameter pizza has the surface area of 5.3m2

    • racer1234 on 10/01/2024 - 10:18

      10000cm2 per m2. 100 x 100 because of the squared bit. 530cm2 == 0.053m2

      • cashless on 10/01/2024 - 10:20

        or 82.15 square inches, since this is obviously a US study

  • Stewardo on 10/01/2024 - 17:23

    What about inflation?
    Average salary in 1999 35k, 2022 92k
    2 pizzas garlic bread and a coke delivered 1999 $18.90 the quality and the size of the product has definitely dropped, but the price hasn’t risen at the same rate as inflation, this is important when you working out if the actual cost adjusted for inflation. I would argue you are getting less product, but the cost to the business has grown at a greater rate.
    Due to the competitive nature of the pizza industry, I’d argue that the product is better value than ever before.

  • bargaino on 10/01/2024 - 18:12

    = (216.77/530.93) x 100 = 40.82

    A lot of wasted effort there. Area is proportional to radius squared, no pi needed.

    (10/13)² = 59% coverage.

    Do we have a spreadsheet of pizza sizes & diameters?
