Answer:
![Volume = 18312.48](https://tex.z-dn.net/?f=Volume%20%3D%2018312.48)
Step-by-step explanation:
Given
![Height (h) = 18mm](https://tex.z-dn.net/?f=Height%20%28h%29%20%3D%2018mm)
![Radius (r) = 18mm](https://tex.z-dn.net/?f=Radius%20%28r%29%20%3D%2018mm)
Required
Determine the volume
The volume of a cylinder is calculated as thus:
![Volume = \pi r^2h](https://tex.z-dn.net/?f=Volume%20%3D%20%5Cpi%20r%5E2h)
Substitute values for r and h
![Volume = 3.14 * 18^2 * 18](https://tex.z-dn.net/?f=Volume%20%3D%203.14%20%2A%2018%5E2%20%2A%2018)
![Volume = 18312.48](https://tex.z-dn.net/?f=Volume%20%3D%2018312.48)
<em>Hence, the volume of the cylinder is 18312.48mm³</em>

Step-by-step explanation:
Given that there are six different toys and they are to be distributed to three different children.
The restraint here is each child gets atleast one toy.
Let us consider the situation as this.
Since each child has to get atleast one toy no of ways to distribute
any 3 toys to the three children each. This can be done by selecting 3 toys from 6 in 6C3 ways and distributing in 3! ways
So 3 toys to each one in 6x5x4 =120 ways
Now remaining 3 toys can be given to any child.
Hence remaining 3 toys can be distributed in 3x3x3 =27 ways
Total no of ways
= 120(27)
= 3240
Answer:
Step-by-step explanation:
The expression -9 + x*2 - 3x*2 + 4x has the following terms:
-9, x^2, -3x^2 and 4x. Please note: x^2 is correct if you meant "the square of x."
a) there is only one constant term; it is -9.
b) there are two terms involving x^2: x^2 and -3x^2. Combining them results in -2x^2.
c) there is only one term involving x: It is 4x.
d) -9 + x*2 - 3x*2 + 4x becomes -2x^2 + 4x - 9. Again, please use " ^ " to indicate exponentiation.
