$\Large \text{area of sector} = \frac{\theta}{360} * \pi r^2$

5. anonymous

60/360 ?

6. anonymous

right?

7. mathslover

Forgetting something there mvrc... pi r^2

8. saifoo.khan

I was just saying for the first part and then its $\frac{ 60 }{ 360} \pi 6^2$

10. anonymous

yeah?

11. anonymous

but idk exactly how to solve it when I get to 60/360 pi36

12. saifoo.khan

Use a calc?

13. anonymous

ik but then do I put 36 /1 and then multiply and divide?

14. saifoo.khan

Which calc do you have?

15. saifoo.khan

(60/360) * pi * (6)^2

16. anonymous

3√3un2 4.5√3un2 9√3un2 theses are the choices it gives me. and I just have a regular one on the pc

17. anonymous

hello?

or @mathslover

20. mathslover

@mvrc1996 what is 'un' there in the options?

21. anonymous

maybe units

22. anonymous

idk

23. mathslover

The answer should be : $$6\pi$$ but that is not given in the options. hmn

24. anonymous

maybe its just 1/6 because its just asking for that section

25. mathslover

Oh yeah we did a mistake @saifoo.khan

26. anonymous

27. mathslover

We found area of sector NOT the area of triangle. Area of triangle = Area of sector - Area of segmennt

28. anonymous

how do I find the area of the segment?

29. mathslover

I have to go mvrc .. it is 11:50 PM here.. sorry . THis will help u for sure : http://www.regentsprep.org/regents/math/geometry/GP14/CircleSectors.htm @hartnn @AravindG and @amistre64 - any of these can help u mvrc. Good luck
