Which is larger? A 6 inch personal pizza or one slice from a 14' inch pizza cut into six slices?

Answer 1

A six inch pizza would have the following area:

A = Pi * r^2
A = 3.14 * 3^2
A = 28.26

The 14 inch pizza would have the following area:

A = Pi * r^2
A = 3.14 * 7^2
A = 153.86

Since you'd only be taking one of six slices of the 14 inch pizza, each slice would be 1/6 of the total area, or:

A = 153.86/6
A = 25.64

So, the 6 inch personal pizza would be slightly larger than the slice from the 14 inch pizza.

Now, I really want pizza.

Answer 2

You don't need to use pi, or worry about whether to work with the radius or the diameter, because it cancels out. The big pizza is bigger by 14 * 14 / (6 * 6) times, that's 196 / 36 or just under 5 1/2, so the personal pizza wins.

Answer 3

6 inch pizza = 28.26in squared. 14 inch slice = 25.643333...in squared. So the 6 inch pizza is larger.

Answer 4

the six inch pizza is larger, with an area of 9pi square inches (versus 8 and 1/6 pi square inches). Re: photographr7's answer, you square the radius not the diameter.

Answer 5

6" pizza
3*3*3.14 = 28.27

Slice of 14' pizza
(7*7*3.14)/6 = 25.66

Go for the personal pizza

Answer 6

you mean
pi*6^2 or (pi*14^2)/6
