Answer:
3562.6 m³
Step-by-step explanation:
In this question, we have to find the volume of a cylinder.
The formula to find the volume of a cylinder is V = πr²h
Plug in your values and solve.
Solve:
V = π(9)²(14)
V = π(81)(14)
V = π(1,134)
V = 3562.566069
Round to the nearest tenths place.
V = 3562.6
Don't forget that the units for volume is already cubed, or to the power of 3.
Your final answer would be 3562.6 m³

Answer:
its either the first option or the third option
Hello!
To solve this, we need to use some trigonometry. We will want to find the length of the bottom. To do so we will need to find those two sides.
First of all, let's find the base of the left triangle. Let's find the tangent of 45.
tan45=1
Therefore, 30/x=1. Just from this, we can see that the base of this triangle is 30.
Now for the other one. Here we have the hypotenuse. As we are looking for the adjacent side, we can use the cosine.
cos60=0.5
This gives us the equation x/80=0.5
From here, we can see that x=40.
Now we add our lengths.
30+40=70
Therefore, the length between the walls is 70 meters.
I hope this helps!
