## anonymous one year ago Solve for pi: C = 2(pi)r.

1. anonymous

You need to get pi onto one side of this equation by isolating it.

2. anonymous

Since we do not know the value(s) of 2, r, nor C, we can just keep them as is.

Here's a demonstration:

4. anonymous

|dw:1435875071909:dw| What do you think is the first thing you should do?

5. anonymous

Hint: Apply inverse operations :)

6. anonymous

divide by 2 or r

7. anonymous

Correct!

8. anonymous

|dw:1435875138471:dw| It doesn't matter which order you do it in.

9. anonymous

Now what do you think you should do?

10. anonymous

so it would be c over 2r = pi

11. anonymous

right?

12. anonymous

Yes.

Thank you
