Let me tell you a secret!
You know how the formula for Circumference is
<span>C = 2πr
</span>
Where r is the radius?
The reason why this formula works the way it does is because of what <span>π IS.
</span><span>π is the ratio of ANY circle's Circumference to it's Diameter.
So you can think of </span><span>π like this:
</span>
Circumference / Diameter.
2r is the same as the diameter. So what you are doing is canceling out the diameter. Similar to what you do in algebra I to solve for x. Then you are just left with the circumference. That's pretty neat!
So, let's get to it!
2<span>πr
</span>
Sadly, you'll most likely need to use a calculator for this problem, but if you are not permitted one then replace <span>π with 3.14.
</span>
What is r?
r = diameter / 2
r = 12 / 2
r = 6
2<span>π6
</span>
If you are allowed to use a calculator then plug it in to it. If not then start doing some long multiplication!

Hey there.
7q - 5
10q + 19
Get the variable to one side.
-5
3q + 19
Isolate the variable.
3q
24
Solve for the variable.
q 8 is your answer.
I hope this helps!
you would round it to 1.7 so aubra would be correct. This is because if the last digit in the number you are rounding id over 4 your round it up. For example 55 would round to 60.
4.34 would round to 4.30
This question is based on greatest common multiple.
Answer:
Cynthia is right that Andy made an error.
Step-by-step explanation:
As per Andy, action dvds are = 
And comedy dvd's are = 
So, in total these become = 
= 
= 
This is not 4/9 as per Andy.
