Is a 12 inch pizza twice as big as a 6 inch pizza?

Answer 1

The circumference of the 12-inch Pizza is twice as big as the 6-inch pizza.

Determine the circumference (C) of both pizzas.

C = pi x d, where d is the diameter

6-inch pizza

C = pi x 6 in = 18.85 in

12-inch pizza

C = pi x 12 in = 37.70 in

Divide the circumference of the larger pizza by the circumference of the smaller pizza.

37.70/18.85 = 2

Answer 2

In terms of length (diameter, radius, circumference, etc): YES

In terms of area on which topping can be placed: NO - it has 4 times the area.

Answer 3

it is twice the diameter but is 4 times as much to eat as area goes as diameter squared

Answer 4

In diameter, yes but in area, no.
