Answer:

1.6 above water

Step-by-step explanation:

Total length of the pipe = length below the water + length above the water

We know the total length of the pipe =3.1  and the length below the water is 1.5 m

3.1 = 1.5 + length above the water

Subtract 1.5 from each side

3.1 -1.5 = 1.5 -1.5 + length above water

1.6 = length above water

Solve for x<br><br> 6x + 3 - 1/2 x = -2x +5
UkoKoshka [18]
<span>First, group the x values together (on one side) and the other values on the other.

  6x + 3 - 1/2 x = -2x +5
6x - 1/2 x + 2x = 5 - 3

Now solve!

     7 and 1/2 x = 2
                      x = 8

This soda can is going to be made from aluminum. How many square centimeters of aluminum are needed if the radius r = 3.5 cm and
kari74 [83]

208.81 square centimeters of aluminium are needed

<em><u>Solution:</u></em>

Given that,

Radius = 3.5 cm

Height = 6 cm

We have to find the square centimeters of aluminum needed

So we have to find the surface area of cylinder

<em><u>The surface area of cylinder is given by formula:</u></em>

A = 2 \pi r(h+r)

Where "r" is the radius and "h" is the height of cylinder

<em><u>Substituting the values we get,</u></em>

A  = 2 \times 3.14 \times 3.5 \times (6+3.5)\\\\A = 21.98 \times 9.5\\\\A = 208.81

Thus 208.81 square centimeters of aluminium are needed
