Answer:
The area of the base is ![10\pi m^2](https://tex.z-dn.net/?f=10%5Cpi%20m%5E2)
Step-by-step explanation:
The volume of a cylinder is calculated using the formula:
![Volume=\pi r^2h](https://tex.z-dn.net/?f=Volume%3D%5Cpi%20r%5E2h)
The volume is given to be:
![V=140\pi m^3](https://tex.z-dn.net/?f=V%3D140%5Cpi%20m%5E3)
The height of the cylinder is h=14 meters.
We substitute these values into the formula to obtain;
![140\pi=\pi r^2\times 14](https://tex.z-dn.net/?f=140%5Cpi%3D%5Cpi%20r%5E2%5Ctimes%2014)
Divide both sides by 14.
![\frac{140\pi}{14}=\pi r^2](https://tex.z-dn.net/?f=%5Cfrac%7B140%5Cpi%7D%7B14%7D%3D%5Cpi%20r%5E2)
![10\pi=\pi r^2](https://tex.z-dn.net/?f=10%5Cpi%3D%5Cpi%20r%5E2)
The area of the base is a circle which is ![\pi r^2=10\pi m^2](https://tex.z-dn.net/?f=%5Cpi%20r%5E2%3D10%5Cpi%20m%5E2)
Well it depends whether or not the ratio was originally simplified. But, assuming that it was not, there would be a total number of 14 people in the room. However, if it was, it would be a multiple of 14.
I'm sorry if this is confusing, I can further explain if you want!
She’s drinking 96 fluid ounces a day, and there’s 8 fluid ounces in a cup so she’s drinking 12 cups of water in a day
Answer:
Step-by-step explanation:
12x - 2 + 20x - 10 = 180
32x - 12 = 180
32x = 192
x = 6
12*6 - 2
72 - 2 = 70
the solution is b
