Are you wondering how to simplify this?

2. anonymous

yes really how to to it on caculator

3. anonymous

really how to input it because spose to sa=850.17cm^2 but when i do it on caculator am not getting that answer

4. anonymous

$\left( 121+11\sqrt{85} \right)\pi$

5. anonymous

Your expression doesn't equal 850.17 cm^2 so maybe your expression isn't quite right.

6. anonymous

SA=11^(2)+11~(11^(2)+8^(2))

7. anonymous

comes to 850.17

8. anonymous

but i never can get that

9. anonymous

121*pi + 11*sqrt(185)*pi?

10. anonymous

Oh you're right - I entered it wrong the first time.

11. anonymous

This is what you should enter into your calculator: $(121+11\sqrt{185})*\pi$

12. anonymous

okay any way can brake it down how you get the answer

13. anonymous

how you get 121 and 185

14. anonymous

11*11 is 121 121 + 64 = 185

15. anonymous

how get 64 lol

16. anonymous

8*8

17. anonymous

yes

18. anonymous

how i get the .17

19. anonymous

When you multiply by pi you'll get extra decimal numbers.

20. anonymous

all okay

21. anonymous

sorry i am putting them in and still not getting that answer with it not entering it in right

22. anonymous

okay so enter it in this order: 11*sqrt(185) + 121 = ..... then take that answer and multiply it by pi (if you have that button) or 3.14 if you don't have a pi button.
