Answer:

radius = 11.00 yd (to the nearest hundredth)

Step-by-step explanation:

Volume of a cylinder = $\pi r^2h$ , where $r$ = radius and $h$ = height

Therefore, for this problem: volume = 6458.98, $\pi$ = 3.14, $h$ = 17

Substituting these values into the above formula:

Volume = $\pi r^2h$ ,

6458.98 = 3.14 x $r^2$ x 17

6458.98 = 53.58 x $r^2$

$r^2$ = 6458.98 ÷ 53.58 = 121

$r$ = √121

$r$ = 11

$r$ = 11.00 yd (to the nearest hundredth)

x = 5

Step-by-step explanation:

I wasn't sure if you needed just x or if you needed the other angles so I did both.

The system of equations is given:

Nutka1998 [239]

Answer:

x=-1/85; y=-283/85; z=2/17

Step-by-step explanation:

Using an algebraic method like elimination or substitution would take a lot of steps which could lead to mistake the calculations. In this case, I decided to use the Gaussian elimination. We can express the system in matrix form as follows:

$\left[\begin{array}{ccc}2&-4&6\\9&-3&1\\5&0&9\end{array}\right] \left[\begin{array}{ccc}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}14\\10\\1\end{array}\right]$

To begin the calculations, we write the system in augmented matrix form and use the Gaussian elimination:

$\left[\begin{array}{ccccc}2&-4&6&|&14\\9&-3&1&|&10\\5&0&9&|&1\end{array}\right]$

By applying the Gaussian elimination, the final matrix is the following:

$\left[\begin{array}{ccccc}1&0&0&|&-1/85\\0&1&0&|&-283/85\\0&0&1&|&2/17\end{array}\right]$

In order to verify the results, it´s enough to substitute the calculated values in the original equations to see if the equalities are correct. Here you can see the verification for all of the equations:

$2(-1/85)-4(-283/85)+6(2/17)=14\\9(-1/85)-3(-283/85)+1(2/17)=10\\5(-1/85)+9(2/17)=1$
