Clock is like a circle, right? So again, you have to walk along the edge.

@dynamiclink can you at least tell me one step ?

4. anonymous

the hand is 8 inch, which is the radius. and the tip of the hand is walking along the circumference|dw:1439305318782:dw|

5. anonymous

Yeah

6. anonymous

Now what ?

7. anonymous

now you need to know how much of that circumference is the tip walking. in other words, how many circles does it walk. in 1 hour it walks 1 circle. makes sense, yeah?

8. anonymous

Yeah it does

9. anonymous

Should I do 3.14*8 ???

10. anonymous

11. anonymous

The formula for the circumference is $2*\pi*R$

12. anonymous

so its 2 times what you said

13. anonymous

Kk so I could just do 16*3.14

14. anonymous

yes

15. anonymous

Kk I'll do that

16. anonymous

17. anonymous
