The radius of a circle is 14 meters. What is the circle circumference

seropon [69]

Step-by-step explanation:

HERE,

redius of a circle (r)=14 meters.

we know that,

$\boxed{\red{\sf{circle~ circumference=2\times \pi \times r }}}$

According to the question, 

circle circumference=

$\tt{2\times \pi \times 14 }$

$\tt{2 \times \dfrac{22}{7} \times 14 }$

$\tt{2 \times \dfrac{22}{\cancel{7}} \times \cancel{14}}$

$\tt{2\times 22 \times 2 }$

$\tt{ 88~meters }$

so, the circumference of that circle is 88 meters.

Solve by substituting the equation y=-x-6 y=x-4 (plz show work)

Elena-2011 [213]

Answer:

x = -1, y= -5

Step-by-step explanation:

y=-x-6

y=x-4

Since both equations are equal to y we can set them equal to each other

-x-6 = x-4

Add x to each side

-x-6+x = x-4+x

-6 = 2x-4

Add 4 to each side

-6+4 = 2x-4+4

-2 =2x

Divide by 2

-2/2 = 2x/2

-1 = x

now find y

y = x-4

y = -1-4

y = -5
