Well I see a rectangle with a length of 9 and width of 8.

6. gabbyalicorn

so 9 x 8 = 72

7. gabbyalicorn

so one of them is B?

8. anonymous

Right. And if that's a quarter circle, then 8 will be the radius. So find the area of the circle with r=8 and then multiply it by 1/4.

9. gabbyalicorn

soz 3.14 x 8 div 4 ?

10. gabbyalicorn

which is 6.28

Area of a circle is $A=\pi*r^{2}$ not $A=\pi*r$

12. gabbyalicorn

soz....3.14 x 64

13. gabbyalicorn

which is 200.96

The choices keep it in pi. So it would be $64\pi$ Now you have to divide by 4 $\frac{64\pi}{4}$

15. gabbyalicorn

i got 50.24

16. anonymous

KEEP IT IN PI $\pi=\pi$ not $\pi=3.14$

17. gabbyalicorn

so 64 div 4?

18. anonymous

And I mean in a format case, not a literal one

19. anonymous

yes 64/4.

20. gabbyalicorn

16 which is also c :3

21. anonymous

$\frac{64\pi}{4}=16\pi$ which yes, is choice c

22. gabbyalicorn

so just B and C :3

23. anonymous

Yep, it would be those two

24. gabbyalicorn

Thank you!

No problem :)
