@gideon737 click on the link it is a screenshot

Okay, well you should know the two equations one for the volume of a cylinder and another for the volume of a cone

8. anonymous

sorry man i cant help with this one

@geerky42

Volume of a cylinder is V=πr2h and volume of a cone is $V=r ^{2}\frac{ h }{ 3 }$

11. anonymous

So now you have to plug in your values

12. anonymous

yes @TobleroneJuses

14. anonymous

Let's start with the cones The height is 4 and the radius is 2. Once we plug the values you should have $V=2^{2}\frac{ 4 }{ 3 }$

15. anonymous

times pi sorry

16. anonymous

So it should equal$V=π2 ^{2} \frac{ 4 }{ 3 }$

17. anonymous

Then you simplify your values *using 3.14 as pi as it suggests in the problem* and what do you get?

18. anonymous

@tbeneka okay is the answer 96.35?

19. anonymous

thats what i got

20. anonymous

did you get that for the whole problem, or just the cone?

21. anonymous

the whole thing

22. anonymous

ohhh give me 2 seconds lol

23. anonymous

there is two cones and one cylinder

24. anonymous

Okay ya that is I got 96.29 but that could be a calculator rounding thing.

25. anonymous

what one would be better to use then?

26. anonymous

hmm try 96.29, I didn't round until I got the final answer, but I'm not 100% sure how your teacher wants it. If they usually want it rounded a different way then do that.

27. anonymous

It says round to the nearest tenth of a cubic inch. so 96.3?

28. anonymous

Oh on the screenshot it says hundredth... if hundredth 96.29 if tenth 96.3

29. anonymous

Oh wait nevermind it does say hundredth. @tbeneka Thank you so much you've helped me allot now I can do these ones now. :)

30. anonymous

YAY \(^.^)/ Sooo glad I could help. You better get 100% lol

31. anonymous

lol yay could you help me on like two more questions that im stuck on?

32. anonymous

Ya I'll try my best

33. anonymous

okay ill post them

34. anonymous

kay just tag me then
