Let
x---------> radius of the cylinder
y---------> the height of the cylinder
we know that
x=2y
[surface area of cylinder]=2*[pi*r²]+2*pi*r*h
surface area=108*pi m²
r=x
h=y
x=2y
108*pi=2*[pi*(2y)²]+2*pi*(2y)*y
108*pi=8*pi*y²+4*pi*y²
108*pi=12*pi*y²
y²=108/12
y²=9----------> y=√9--------> y=3 m
x=2y-------> x=2*3-----> x=6 m
the answer is
the height of the cylinder is 3 m
Option C: The solution is ![7x^{2} +2x-6](https://tex.z-dn.net/?f=7x%5E%7B2%7D%20%2B2x-6)
Explanation:
The given expression is ![(7x^{2} -3x)+(5x-6)](https://tex.z-dn.net/?f=%287x%5E%7B2%7D%20-3x%29%2B%285x-6%29)
We need to solution of the given expression.
The solution of the given expression can be determined by adding the two expressions.
Let us remove the parenthesis.
Thus, we have,
![7x^{2} -3x+5x-6](https://tex.z-dn.net/?f=7x%5E%7B2%7D%20-3x%2B5x-6)
Adding the like terms, we have,
![7x^{2} +2x-6](https://tex.z-dn.net/?f=7x%5E%7B2%7D%20%2B2x-6)
Thus, the solution is ![7x^{2} +2x-6](https://tex.z-dn.net/?f=7x%5E%7B2%7D%20%2B2x-6)
Hence, Option C is the correct answer.
Answer:
1.2 liters
Step-by-step explanation:
7/7 of a liter is one liter. and you still are only at 7. you need to get to 9 you and 2 1/7 liters and that becomes 9/7 liters which = 1.2
Answer:
140?
Step-by-step explanation:
40 percent of 350 is 140 so I assume its 140.
I don’t think there’s a solution
