V= pi r^2=3.14*r^2
our V=14,542 m^3
14,524=3.14*r^2 divide both sides by 3.14
4625.47=r^2
r =

r=68

Answer:
4.7/5
Step-by-step explanation:
Answer:
Always
Step-by-step explanation:
The definition of a perpendicular line is that it intersects another at a 90 degree angle. Using this, by verticals, the opposite corner angle must also be 90-degrees, and since one side of a line is 180 degrees, 180-90 = 90, which ensure the rest of the angles will be 90 degrees too.
To calculate the value of x, you can apply:
Tan(α)=Opposite leg/Adjacent leg
In this case, the opposite leg is "x", and the adjacent leg is 15. The angle α is 30° (α=30°)
When we substitute this values, we obtain:
Tan(α)=Opposite leg/Adjacent leg
Tan(30°)=x/15
x=(15)(Tan(30°))
x=5√3
