Hi again!

2. Anikate

hi :D

3. anonymous

Since AO is equivalent to AB it is a isosocles triangle.

4. anonymous

SO from that we can calculate angle o and angle b are 40 degrees

5. anonymous

do you know the sector formula?

6. anonymous

$\frac{ x }{ 360 } \times \pi r^2$

7. Anikate

sorry if i dont respond sometimes, my connection is terrible. My computer is as far as possible away from our network router, literally at the other corner of the house. and parents dont want to spend money on a dual band network router.

x would be 40, as we found angle O was 40. this means the shaded area is 40 degrees of the whole 360 degrees of the circle.

9. anonymous

You get me?

10. anonymous

so $\frac{ 40 }{ 360 } \times \pi 6^2$

11. anonymous

then $\frac{ 1 }{ 9 } \times 36$

12. anonymous

sorry 36 pi

13. anonymous

so then once you multiply 1/9 and 36, you get 4, which then would equal 4 pi

14. anonymous

So your answer is B, $4 \pi$
