Hello!
The problem says to use the equation
[tex]V = \frac{4}{3} * 3.14 * r^{3} [/tex]
V is volume
r is radius
Put in the values you know
[tex]V = \frac{4}{3} * 3.14 * 6^{3} [/tex]
Cube the number
[tex]V = \frac{4}{3} * 3.14 * 216[/tex]
Multiply
V = 904.32
The answer is 904 cubic inches
Hope this helps!
