Answer:

B. 6.3 inches.

Step-by-step explanation:

I'll use 2πr for both sides of this.

Pie:

2 * 3.14 * 8

16 * 3.14

50.24 inches for the pie

Container:

2 * 3.14 * 9

18 * 3.14

56.52 inches for the container

Difference:

56.52 - 50.24

6.28-inch difference, which rounds to 6.3 inches. B is our answer.
