XY = (40/360)*(Circumference)

4. needmathhelp7

I got 81?

@jim_thompson5910

6. jim_thompson5910

what did you get for the circumference?

7. needmathhelp7

40?

8. needmathhelp7

wait how do u find the circumference?

@jim_thompson5910 @Mertsj

Well, I see that the angle is 40 degrees. I'm trying to think what part of the entire circle that is. How many degrees are in the whole circle?

11. jim_thompson5910

C = 2*pi*r C = 2*3.14*9 C = ???

12. needmathhelp7

I got 508.98?

13. needmathhelp7

14. Mertsj

That seems like a big answer. How did you get it?

15. needmathhelp7

I did: 360/40= 4 then I did: 2 x 3.14 x 9= 56.52 then I multiplied them both (4 x 56.52) and I got 508.98

sry the site isn't working for me, is it working for you?

18. jim_thompson5910

well now it is, but its off and on...

19. needmathhelp7

now it finally is! Lol yeah

20. needmathhelp7

it's fine! I'm having the same issue

21. jim_thompson5910

circumference is 56.52

22. jim_thompson5910

so XY = (40/360)*(Circumference) XY = (40/360)*(56.52) XY = ???

23. needmathhelp7

actually for 360/40 i got 9 :) I got 508.68

24. jim_thompson5910

you're dividing the wrong way

25. jim_thompson5910

it's not 360/40 it should be 40/360

26. needmathhelp7

OH that made SUCH a big difference..I didn't think that mattered! Haha

27. needmathhelp7

oops xD Lol I got 6.28 as my answer?

28. jim_thompson5910

you can only flip the terms if you are either adding or multiplying

29. jim_thompson5910

not dividing or subtracting

30. jim_thompson5910

me too
