Answer:

25.1cm

Step-by-step explanation:

since circumference = $\pi$ d and d=2r

c= $\pi$ (2*4)

c=8 $\pi$

c=25.132741229

c=25.1cm

HELP 20 POINTS!

Butoxors [25]

For the first blank where it asks for the perimeter, the perimeter is all the outside sides of a shape added up. So, 6 + 1 + 2 + 4 + 4 + 5 = 22.

For the second blank, you just multiply the entire perimeter by 5, so, 22 times 5=110.

For the third blank, it is basically the same as the previous question. The answer is 5.

For the fourth blank, it is the same perimeter as the first blank, but instead of centimeters, it is in k. So, 22k.

Hope this helped! :)

How to graph 14x+18y=126

Burka [1]

We need to rearrange this into $y=my+c$
Subtract 14x from both sides
$18y=-14x+126$
Divide both sides by 2
$9y=-7x+63$
Divide both sides by 9
$y=\frac{-7x+63}{9}=\frac{-7x}{9} +\frac{63}{9}$
Plot the point (0, 63/9)
Then pick some x values and put them into the equation to find the respective y values
Then plot those points
Finally join up those points
