Answer:
The volume of c. figure is equal to 90 cm³
Step-by-step explanation:
These are the cuboids
The volume of a cuboid = l×b×h
A. 2×6×5
=> 60 cm³
B. 8×2×4
=> 64 cm³
C. 5×6×3
=> 90 cm³
D. 3×7×2
=> 42 cm ³
so, the volume of c. cuboid is equal to 90 cm ³
There are 48 available subjects. Researchers should select 4 of them for their experiment.
We should find the number of possible different random samples. The order of the selected subjects is not important. This means that we need to find how many different combinations of subjects from total 48 are possible. <span>A </span>formula<span> for the number of possible </span>combinations<span> of </span>r<span> objects from a </span>set<span> of </span>n<span> objects is: n!/r!(n-r)!. In our case n=48 and r=4:
C=48!/44!*4!=48*47*46*45*44!/44!*4!=</span><span>48*47*46*45/4*3*2*1=4669920/24=

Answer:
Height = 7 meters
Step-by-step explanation:
Equation:
To work out the height, you need to know the formula for the volume of a cone which is:
Explaining variables:
- mathematical constant.
- radius of the cone
- height of the cone
- volume of the cone
Working out the height:
We are looking for the height, so let's re-arrange the equation.
We are given the height, volume and diameter.
To work out the radius we have to know that 
. So the radius is 
m.
Now let's put everything in the equation for the height to work it out.
meters.
Therefore, the height of the cone is 7 meters.
It is 2. (4x - 1) which is false!
