Answer:
C = 6.28r
Step-by-step explanation:
If the circumference of a circle is C, then C = 2(3.14)r, where r is the radius.
Then C = 6.28r
One way is that you can just factor it out: (x+2)(x+2)(x+2)
For the first pair, you get
.
Then do
*
That will be
So the answer is 6
1) You divide all the numbers that need to be divided
2) Move constant to the right
3) Add your numbers
And it will get you your answer = y=10.9
Here’s another answer if you didn’t understand the other one
Divide your numbers- y-4/10=21/2
Move constant to the right- y-0.4=10.5
Add the numbers- y=10.5+0.4
Hopefully that helped :)
