Answer:
Step-by-step explanation:
Hello There!
It says the tree has a cone like structure
The formula for volume of a cone is
where r = radius and h = height
note it says to use 3.14 for pi
so given the dimensions all we have to do is plug in the values into the formula
Our last step is to round to the nearest foot
So we can conclude that the tree has a volume of 25.13ft³

Explanation:
The inequality sign has an "or equal to", which means the boundary line will be solid. We can rule out choices B and C because they have dashed boundary lines.
A solid boundary line means that points on the boundary are part of the solution set.
Now let's see what happens when we plug in a point like (x,y) = (4,0). This will tell us how to shade the blue region.
This is false because -20 is not larger than -1. It's the other way around.
This tells us the point (4,0) is not in the blue shaded region, and it's not on the boundary line either. We can rule out choice A because of this.
The only thing left is choice D, which is the final answer. I recommend plugging a point from this region into the inequality to confirm we have a true statement.
