Since you have 7 liters in all you know that 7 minus 2 is 5.
2*14% + 5*x% = 7*34%
0.28 + 5*x% = 2.38
5*x% = 2.38 - 0.28
5*x% = 2.10
x% = 0.42
x = 42%
Chandra must add 5 liters of 42% solution.
B, the other choices are too short to even be considered
The correct answer is 5 5/9. Hope this helps!!
Answer:
Therefore,
Volume of the cylinder is 24501.42 m³.
Step-by-step explanation:
Given:
Height of Cylinder = 27 m
Diameter, d = 34 m
![Radius = \dfrac{d}{2}=\dfrac{34}{2}=17\ m](https://tex.z-dn.net/?f=Radius%20%3D%20%5Cdfrac%7Bd%7D%7B2%7D%3D%5Cdfrac%7B34%7D%7B2%7D%3D17%5C%20m)
Volume of a Cylinder = ?
Solution:
We know that
![\textrm{Volume of a Cylinder}=\pi (Radius)^{2}\times Height](https://tex.z-dn.net/?f=%5Ctextrm%7BVolume%20of%20a%20Cylinder%7D%3D%5Cpi%20%28Radius%29%5E%7B2%7D%5Ctimes%20Height)
Substituting the given values in formula we get
![\textrm{Volume of a Cylinder}=3.14 (17)^{2}\times 27=24501.42\ m^{3}](https://tex.z-dn.net/?f=%5Ctextrm%7BVolume%20of%20a%20Cylinder%7D%3D3.14%20%2817%29%5E%7B2%7D%5Ctimes%2027%3D24501.42%5C%20m%5E%7B3%7D)
Therefore,
Volume of the cylinder is 24501.42 m³.
