Which gives you more pizza? 1 16" pizza or 2 8" pizzas?

Question

for those of you who want to get technical...replace the word pizza with perfect circle.

Answer 1

(pi)r^2
16 inch = 200.96 square inches
2 * 8 inch = 100 sq inch

definatly the 16 inch, it makes sense because 2 8 inchers are the same width as one 19 inch when side to side, but they are half the height. the 2 8 inchers sit side by side in the area of the 16 inch.

I can't believe how many people thought it was the 2 8 inches or they were the same!! The mistake comes from doubling the radius before you square it when calculating the area:
2(pi)(r^2) correct vs. wrong (pi)(2r)^2

not that anyone cares!

Answer 2

16''
Pi x Radius(8) x Radius(8)=201.061

2 8''
Pi x Radius(4) x Radius(4) x Number of pizzas(2) = 100.530



Hence, 1 16'' pizza is bigger than 2 8'' pizzas.

Answer 3

One 16" pizza will yield more pizza because the area is greater than two 8" pizzas.

Answer 4

There are many unmentioned variables:
1. Are they both square? Both round? One square, one round? Other shape (I have seen others)?
2. How much area is the crust accounting for?
3. frozen pizza or hot out of the oven?--this can make a difference.
4. Are we no-topping pizzas or extra toppings?
5. Etc.

Answer 5

2 8" pizza

Answer 6

2 8's

Answer 7

They're both the same. 1 x 16 is 16. 2 x 8 is 16. So therefore, both pizzas would be equivilant.

Answer 8

area if 16" pizza = 3.1415 (pi) x 8x8 = 201.056
area of 2 8" pizza = 3.1415 (pi)x4x4x2= 200.528

more pizza in 1x16" than 2 8" pizzas

Answer 9

16" Find the surface area. a 16" has more surface area then 2 8", hence, more pizza

Answer 10

2 8"
