Question 317205
First, find the area of the round pizza:


A=Pi*r^2
A=Pi*(7)^2
A=49*Pi


The area of a single slice would be 1/12 of the whole area:

Aslice = 49*Pi/12 = 12.83 inches squared



Now find the area of the square pizza:


A=x^2
A=12^2
A=144


We are cutting it into 9 pieces, so to find the area of one piece:

Aslice = 144/9
Aslice = 16 inches squared


So the square slice is larger, by (16-12.83)  3.17 square inches.
