Answer:

<h2><em><u>18</u></em><em><u>.</u></em><em><u>2</u></em><em><u> </u></em><em><u>cm</u></em></h2>

Step-by-step explanation:

<em><u>Given</u></em><em><u>, </u></em>

Radius of the circle = 2.9 in.

<em><u>Therefore</u></em><em><u>, </u></em>

Circumference of the circle

= 2\pi r

= 2 \times 3.14 \times 2.9 \: cm

= 18.212 cm

<em><u>As</u></em><em><u>,</u></em>

It has asked for nearest tenth so it will be,

18.2<em><u>1</u></em>2 cm

<em><u>Since</u></em><em><u>,</u></em><em><u> </u></em><em><u>there</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>1</u></em><em><u> </u></em><em><u>in</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>hundredth</u></em><em><u> </u></em><em><u>digit</u></em><em><u> </u></em><em><u>so</u></em><em><u> </u></em><em><u>it</u></em><em><u> </u></em><em><u>will</u></em><em><u> </u></em><em><u>round</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>0</u></em><em><u>.</u></em>

<em><u>Hence</u></em><em><u>,</u></em>

<em><u>18</u></em><em><u>.</u></em><em><u>2</u></em><em><u> </u></em><em><u>cm</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>required</u></em><em><u> </u></em><em><u>c</u></em><em><u>ircumference</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>circle</u></em><em><u> </u></em><em><u>rounded</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>nearest</u></em><em><u> </u></em><em><u>tenth</u></em><em><u>. </u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>

The formula for circumference is 2*pi*r
We plug in these values and get 2*pi*2.9
Or 18.2 in

What is the solution to this system of equations?
Ede4ka [16]

Answer:

First choice.

Step-by-step explanation:

You could plug in the choices to see which would make all the 3 equations true.

Let's start with (x=2,y=-6,z=1):

2x+y-z=-3

2(2)+-6-1=-3

4-6-1=-3

-2-1=-3

-3=-3 is true so the first choice satisfies the first equation.

5x-2y+2z=24

5(2)-2(-6)+2(1)=24

10+12+2=24

24=24 is true so the first choice satisfies the second equation.

3x-z=5

3(2)-1=5

6-1=5

5=5 is true so the first choice satisfies the third equation.

We don't have to go any further since we found the solution.

---------Another way.

Multiply the first equation by 2 and add equation 1 and equation 2  together.

2(2x+y-z=-3)

4x+2y-2z=-6 is the first equation multiplied by 2.

5x-2y+2z=24

----------------------Add the equations together:

9x+0+0=18

9x=18

Divide both sides by 9:

x=18/9

x=2

Using the third equation along with x=2 we can find z.

3x-z=5 with x=2:

3(2)-z=5

6-z=5

Add z on both sides:

6=5+z

Subtract 5 on both sides:

1=z

Now using the first equation along with 2x+y-z=-3 with x=2 and z=1:

2(2)+y-1=-3

4+y-1=-3

3+y=-3

Subtract 3 on both sides:

y=-6

So the solution is (x=2,y=-6,z=1).
