Answer:
-3 < x ≤ 7
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We can see from the graph that our x-values that can be inputted are from -3 to 7. Since -3 is an open dot, we cannot include this in our domain.
∴ -3 < x ≤ 7
24416.64
Based on the standard formula,4/3×π×r^3
The π has been given already and r=18
4/3×3.14×18^3
V=24416.64
