No, right?

5. anonymous

Like what are the steps?

6. anonymous

No that isn't the answer.. You have to plug in the information they have given you. The r in this formula represents 12, the radius. While m represents the measure of the length they gave you, 10pi.

7. anonymous

So:$144 \left( 10\pi \right) \over 360$

8. anonymous

1440pi over 360?

9. anonymous

a=pir^2*10pi/2pir=5pir

10. anonymous

Could someone just write out the entire answer so that i can understand the steps easier? Thanks

11. anonymous

@Emah Could you help?

12. anonymous

A=pi r^2/2 pi r*10 pi=5 pi r=5 pi 12=60 pi

13. anonymous

Sorry but im not following..Maybe make it easier to read?

14. anonymous

I'm sorry, I know how to do this, but I can't figure out the 10pi being the measure.. Usually its a degree..

15. anonymous

A=(πr^2)/2πr*10π=5πr=5π*12=60π

16. anonymous

does the / mean a fraction like (pi)(r)^2 over something else?
