Answer:

When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field. The piece of iron has become a magnet. Some substances can be magnetized by an electric current.

Hi! how do i find surface area of a cylinder? for some reason i can’t get the right answer

asambeis [7]

$SA=2\pi r^2+2\pi rh$

Use the formula above to find the surface area of a cylinder.

For the given cylinder the given data is the height (6mi) and diameter (16mi), use the diameter to find the radius:

$\begin{gathered} r=\frac{d}{2} \\ \\ r=\frac{16mi}{2}=8mi \end{gathered}$

Surface area:

$\begin{gathered} SA=2\pi(8mi)\placeholder{⬚}^2+2\pi(8mi)(6mi) \\ SA=128\pi mi^2+96\pi mi^2 \\ SA=224\pi mi^2 \end{gathered}$ Then, the surface area of the given cylinder is: 224π square miles

How do I solve this equation for x?

lara31 [8.8K]

Answer:

The answer is x = -32

Step-by-step explanation:

In order to find the value of x, e must first distribute the 6 into the parenthesis.

6(x - 7) = 8x + 22

6x - 42 = 8x + 22

Now we will add/subtract values so that all x values are on the right and all number values are on the left.

6x - 42 = 8x + 22

-42 = 2x + 22

-64 = 2x

Now to get the final answer, divide both sides by 2.

-32 = x
