Find the lateral surface area of the cylinder. Round your answer to the nearest tenth.
viktelen [127]

Answer:

72 pi

Step-by-step explanation:

Think of the lateral surface area as a label on a soup can. When you roll it out, then the circumference becomes the length and the height of the cylinder becomes the width or vise versa. So if 2(pi)(r) is the formula for the circumference, then that is 8. 8*9 is 72 and you multiply that by pi to get 72 pi

Which of the following equations has the same solutions as the equation 3x+2y=-12? Check all that apply.
grigory [225]
ANSWER

B,C,E \: and \: F



EXPLANATION

The given equation is
3x + 2y =  - 12

The solution to this equation can be found by making y the subject.

\Rightarrow \: 2y =  - 3x - 12


\Rightarrow \: y =  -  \frac{3}{2} x - 6
This equation has infinitely many solution. Any real value we choose for x, there is a corresponding y-value.



To find which of the given options also has the same solution, we make y the subject.


A

3x - 2y = 12


\Rightarrow \:  - 2y =  - 3x  +  12


\Rightarrow \: y =   \frac{3}{2} x   - 6


This is not the same as the given equation.


B


- 3x - 2y = 12


\Rightarrow \:  - 2y =   3x  +  12


\Rightarrow \: y =   -  \frac{3}{2} x   -  6

This solution is the same as the one given.




C.
15x + 10y =  - 60


\Rightarrow \: 10y =  - 15x - 60



\Rightarrow \: y =  -  \frac{15}{10} x -  \frac{60}{10}


\Rightarrow \: y =  -  \frac{3}{2} x - 6


This is the same as the above solution.


D.
6x + 2y =  - 12



\Rightarrow \: 2y =  - 6x - 12


\Rightarrow \: y =  -  3 x - 6

This is not the same as the one given.


E.

6x + 4y =  - 24


\Rightarrow \: 4y =  - 6x - 24


\Rightarrow \: y =  -  \frac{6}{4} x -  \frac{24}{4}

\Rightarrow \: y =  -  \frac{3}{2} x - 6

This is the same as the one given.


F.

1.5x + y =  - 6


\Rightarrow \: y =  - 1.5x - 6


\Rightarrow \: y =  -  \frac{3}{2} x - 6

Thus is the same as the one given.



G.
x +  \frac{2}{3} y =  - 12


\Rightarrow \:  \frac{2}{3} y =  - x - 12


\Rightarrow \: y =  -  \frac{3}{2} x - 12 \times   \frac{3}{2}

\Rightarrow \: y =  -  \frac{3}{2} x - 18


This is not the same as the one given.
