V=pi r2.h
Basically you find your radius and height
Answer:
9.5
Step-by-step explanation:
I'm not sure but I think 9.5 x 6 is 57 degrees so I'm guessing its 9 1/2 or 9.5
<h2>Answer:</h2>
A prism is a solid object having two identical bases, hence the same cross section along the length. This is a rectangular prism its base is a rectangle. multiplying the three dimensions of a rectangular prism: length, width and height, gives us the volume of a prism:
![V=L\times W\times H](https://tex.z-dn.net/?f=V%3DL%5Ctimes%20W%5Ctimes%20H)
Therefore, Associative Property can be used to mentally find the volume of the prisms shown by selecting the easier way of the multiplication. For instance, we can say that:
![L=5cm \\ \\ W=18cm \\ \\ H=20cm](https://tex.z-dn.net/?f=L%3D5cm%20%5C%5C%20%5C%5C%20W%3D18cm%20%5C%5C%20%5C%5C%20H%3D20cm)
In whose case:
![V=5\times 18\times 20](https://tex.z-dn.net/?f=V%3D5%5Ctimes%2018%5Ctimes%2020)
To operate this mentally is not an easy way, but<em> what if we rotate this shape? </em>so we say that:
![L=18cm \\ \\ W=20cm \\ \\ H=5cm](https://tex.z-dn.net/?f=L%3D18cm%20%5C%5C%20%5C%5C%20W%3D20cm%20%5C%5C%20%5C%5C%20H%3D5cm)
Then, the volume can be found as:
![V=18\times 20\times 5](https://tex.z-dn.net/?f=V%3D18%5Ctimes%2020%5Ctimes%205)
There are two forms of finding the result. First, multiplying 18 by 20 and then the result by 5, but as in the previous case this is a tricky way to do mentally:
![V=(18\times 20)\times 5](https://tex.z-dn.net/?f=V%3D%2818%5Ctimes%2020%29%5Ctimes%205)
Hence, here we can use Associative Property multiplying 20 by 5 and then the result by 18:
![V=18\times (20\times 5)](https://tex.z-dn.net/?f=V%3D18%5Ctimes%20%2820%5Ctimes%205%29)
This last arrangement is easier because 20 x 5 is easy to remember given that the result is 100. Then, by multiplying this result by 18 then we get 1800.
Answer:
This is experimental fraction question
We start with a high fraction and work downwards to a lower fraction
Reduce 10/16; = 6/12 = 1/2 observation = the fraction gets smaller by 1/5
Reduce 10/12 = 6/9 = 1/3 observation = the fraction gets smaller by 1/4
Reduce 8/8 = 3/2 observation = the fraction gets smaller by 1/3
We notice that when the fraction is whole number it reduces by 1/3
When the fraction is 3/4 it reduces by 1/4
When the fraction is 5/8 or 10/16 it reduces the fraction by 1/5
When the fraction is already half
We can prove it reduces again by a smaller than 1/5 number
1/2 = 10/20 = reduction = 6/15 = it has reduced by 3/15 = 1/6 to 1/7
This is because the numerator is reduced 40% and the denominator is reduced by 25%
