hey sorry i left the page open and was browsing some other stuff, hold on

5. anonymous

Thank you :D

6. aaronq

take the area the circle and divide by half (semi-circle) and add the area of the triangle to it

7. anonymous

How would I get the area?

8. aaronq

so $\frac{ \pi r^2 }{ 2 } + \frac{ b \times h }{ 2 }$

9. aaronq

area of circle is the radius time pi squared

10. anonymous

So it would be, one sec

11. aaronq

damn i meant pi times the radius squared, sorry

12. aaronq

what is that?

13. anonymous

31.945104? Sorry divided by 2 on the first one

14. anonymous

Right?

15. aaronq

no thats wrong

16. anonymous

x.x

17. anonymous

What did I do wrong I did 3.6/2 x 3.14=N^2

18. aaronq

n^2?

19. anonymous

*note* I put in the wrong # the numbers are 4.8 and 3.6 *note*

20. aaronq

so whats the area of the semi circle?

21. anonymous

N=5.692

22. anonymous

31.945104 is what I got...

23. anonymous

Never mind, I got it.

24. aaronq

i got for the semi circle = 5.0868
