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:
BC, DB, CD
Step-by-step explanation:
The side opposite the largest angle must be the largest side and the side opposite the smallest angle must be the shortest. 96 degrees is opposite CD and 30 degrees is opposite BC.
First aquarium dimensions:
Length = 6 m.
Width = 4 m and
Height = 2 meter.
Second aquarium dimensions:
Length = 8 m.
Width = 9 m and
Height = 3 meter.
We know formula for volume of a cuboidal box = Length*Width*Height.
Plugging values of length, width and height of first aquarium in formula of volume. We get
V1 = 6*4*2 = 48 m^3.
Plugging values of length, width and height of second aquarium in formula of volume. We get
V2 = 8*9*3 = 216 m^3.
In order to find the total cubic meters of space do the sea turtles have in their habitat, we need to add both volumes.
Therefore, Total voulme of both aquarium = V1 +V2 = 48+216 = 264 m^3.
Therefore, total 264 m^3 cubic meters of space the sea turtles have in their habitat.
Answer:
53
Step-by-step explanation:
42/6=7
7*5=35
18+35=53
As an improper fraction, the simplified answer would be 9/7 after you divide both top and bottom by 10
------------------------
If you need a mixed number, then 9/7 converts to 1 & 2/7 because
9/7 = 1 remainder 2
If you had 9 cookies and 7 friends, then each friend gets 1 whole cookie, and there will be 2 left over.
