Answer:
The 18 inch slice is bigger because it has a larger area than the 12 in slice.
Step-by-step explanation:
Find the radius of each pizza then find the area of each pizza.
The radius is half the diameter
The 12 inch pizza has a diameter of 12 in. Half of 12 in. is 6 in.
The 18 inch pizza has a diameter of 18 in. Half of 18 in. is 9 in.
Now find the area of each pizza. Then find the area of each slice by dividing the area by the number of slices.
12 in pizza
[tex]A = \pi r^{2}\\A=3.14(6^{2} )\\A= 3.14 (36)\\A=113.04\\\\113.04/4 = 28.26[/tex]
18 in pizza
[tex]A = \pi r^{2}\\A=3.14(9^{2} )\\A= 3.14 (81)\\A=254.34\\\\254.34/8 = 31.7925[/tex]
The 18 inch slice is bigger because it has a larger area.
