## kaylala one year ago if point P rotated 1.5 times along a circle of radius 1 unit then P travels _______ units

what does r n and s stand for?

if point P rotated 1.5 times along a circle of radius 1 unit then P travels _______ units

3. kaylala

can you actually give me the question the exact way it was given to you

5. kaylala

well contact your teacher the idiot that gave you this problem doesn't know how to explain it properly

7. kaylala

lol

I assume they mean 1.5 times around the circle. find how far 1.5 loops around the circle is. (1 loop is the circumference)

11. kaylala

180 degrees ? @phi

12. phi

I think they want the distance around the circle 1.5 times. First step: what is the distance if you go around the circle once? (the distance is called the circumference)

13. kaylala

360? @phi

14. phi

180 and 360 sound like degrees. see http://www.mathplanet.com/education/pre-algebra/more-about-equation-and-inequalities/calculating-the-circumference-of-a-circle

15. kaylala

i see

16. kaylala

but i still dont know how to do this?

17. kaylala

@phi

18. phi

Do you see what the formula for the circumference (called C) is ?

19. kaylala

yup c=2 pi r

20. phi

now look at your question. what is r ?

21. kaylala

1

22. phi

and what number do you use for pi ?

23. kaylala

3.14

24. phi

now use those numbers in your formula c= 2*pi*r replace pi with 3.14 and r with 1 c= 2*3.14*1 what is c ?

25. kaylala

c=6.28

26. phi

that is the distance once around the circle. they want the distance if you go 1.5 times around the circle. that means multiply c by 1.5

27. kaylala

oh i see = 9.42 ? @phi

28. kaylala

thank you
