Answer:

1332.035 millimeters

Step-by-step explanation:

If you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14. You can also work out the circumference of a circle if you know its radius. Remember that the diameter is double the length of the radius. We already know that C = πd. If r is the radius of the circle, then d = 2r. So, C = 2πr.

Find three consecutive even integers whose sum is −24

labwork [276]

Answer: $-10,-8,-6$

Step-by-step explanation:

Let be:

$x$ , $x+2$ and $x+4$ the three consecutive even integers whose sum is -24

Then, we can write this expression:

$x+(x+2)+(x+4)=-24$

Now, we must solve for "x":

$3x+6=-24\\\\3x=-24-6\\\\3x=-30\\\\x=\frac{-30}{3}\\\\x=-10$

Then you get that the others integers are:

$x+2=-10+2=-8$

$x+4=-10+4=-6$

Therefore, the three consecutive even integers whose sum is -24 are:

$-10,-8,-6$
