Answer:
0.48
Step-by-step explanation:
You use the formula V=πr2 h/3
Answer:
Step-by-step explanation:
The answer is c.
Proportional means a relationship of y = a constant multiplied by x
In this case, the constant is 7.
i.e. y = 7x
So if
x is 3, y is 21
x is 5, y is 35
x is 7, y is 49
and so on...
And there you have it.
I believe you would have to multiply both 25 and 20 and what ever number you get dived by 100 if the numbers to high multiply aging or subtract the number (if it's wrong I'm really not good at my math I'm sorry)
Hey there!
Assuming you meant
![5r^2 - 12 = 68](https://tex.z-dn.net/?f=%205r%5E2%20-%2012%20%3D%2068%20%20)
If so, follow these steps so it can be a little bit easier to solve
Firstly, we have to
by
on each of your sides
![5r^2 -12 +12 \\ \\ 68 + 12](https://tex.z-dn.net/?f=%205r%5E2%20-12%20%2B12%20%5C%5C%20%5C%5C%2068%20%2B%2012%20%20)
![5r^2 = 5r^2 \\ \\ 68 + 12 = 80](https://tex.z-dn.net/?f=%205r%5E2%20%3D%205r%5E2%20%5C%5C%20%5C%5C%2068%20%2B%2012%20%3D%2080%20%20)
We get: ![5r^2 =80](https://tex.z-dn.net/?f=%205r%5E2%20%3D80%20%20)
Now, we have
by
on each of your sides
![\frac{5r^2}{5} = \frac{80}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5r%5E2%7D%7B5%7D%20%3D%20%5Cfrac%7B80%7D%7B5%7D%20%20)
![\frac{80}{5} = 16](https://tex.z-dn.net/?f=%20%5Cfrac%7B80%7D%7B5%7D%20%20%3D%2016%20%20)
We get: ![r^2 = 16](https://tex.z-dn.net/?f=%20r%5E2%20%3D%2016%20%20)
± ![\sqrt{16}](https://tex.z-dn.net/?f=%20%5Csqrt%7B16%7D%20%20)
Therefore , your answer is:
±![4](https://tex.z-dn.net/?f=%204%20%20)
Good luck on your assignment and enjoy your day!
