Answer: There are 3.5 metric tons will be supported by a column 8 m high and two thirds m in diameter.
Step-by-step explanation:
Since we have given that
Height of columns of arena = 9 m
Diameter = 1 m
Load = 14 metric tons
Since Load is directly varies as the fourth power of the diameter 'd', and inversely as the square of the height.
so, Mathematically, it is expressed as

If the height of columns = 8 m
Diameter = 
So, Load would be

Hence, there are 3.5 metric tons will be supported by a column 8 m high and two thirds m in diameter.

Answer:
1 over 32
Step-by-step explanation:
you multiply 3 by 18 to get 64 then simplify by dividing by 2
Draw a diagram
the diagram is a right triangle
use the tangent function
tan=opposite/adjacent
call the angle "θ"
tanθ=15/57
tanθ=0.2631579
use the arctan function on your calculator
tan-1θ=0.2631579
θ=14.74356312º or 14º 44' 36.827"
