Answer:
One sector of the party wheel
Step-by-step explanation:
#Determine the areas of the two different shapes to validate.
-For the square pizza:
[tex]A=s\times s\\\\=6\times 6\\\\=36\ in^2[/tex]
-For the a sixth slice of a circular pizza:
[tex]A=\frac{1}{6}\pi r^2\\\\=\frac{1}{6}\pi \times (18/2)^2\\\\=42.41 \ in^2[/tex]
#We then compare the two calculated areas to determine which is larger.
[tex]42.41>36[/tex], hence, the one sector of the party wheel is larger.
