Answer:
2400000pi cubic meters of dirt had to be removed to build the Chunnel.
Step-by-step explanation:
Volume of a <em>half-cylinder</em> can be stated as:
where
- r is the radius (here the height)
- h is the height ( here the lenght)
Thus, one half-cylinder tunnel volume is: 
=800000pi
Since there are 3 half-cylinder tunnels, 3×800000pi=2400000pi cubic meters of dirt had to be removed to build the Chunnel
Answer:
Step-by-step explanation:
Let the number of small boxes = x
and the number of large boxes = y
Total number of boxes = 24
Therefore, equation will be,
x + y = 24 ------ (1)
Since, volume of the smaller boxes = 9 cubic feet
And the volume of larger boxes = 24 cubic feet
Therefore, total volume of the boxes = (9x + 24y)
Since combined volume of all boxes = 441 cubic feet
Therefore, equation will be,
9x + 24y = 441 ------ (2)
Let the number be x.
2*(x-4) < (x+5).
2x -8 < x +5
2x-x < 5 +8
x<13.
The number is less than 13.
That's it. Cheers.
