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.
i think it would be y+8=1/5(x+3)
Step-by-step explanation:
point slope formula is y-y1=m(x-x1)
slope=m
m=1/5
Subtract 27 and you can get a relationship between b and c. Without additional information, that's the best you can do.
3b +c = -43
