Ответ:
(B) Between 6 and 9 minutes, Sameen's distance from work is decreasing
Step-by-step explanation:
Looking at the graph, we want to make sure we are looking at the right axis.
The x-axis, the horizontal one, is minutes.
The y-axis, the vertical one, is distance from work.
We can see that while x is between 6 and 9 minutes, the graph slopes downwards. This signifies a decrease in distance from work.
So between 6 and 9 minutes, Sameen's distance from work is decreasing.
Hope this helped!

we have
volume of cone =1/3 πr²h=1/3×π×4²×7ft³
so
v=1/3 π(4²)(7)ft³
