## myininaya Group Title Find the volume for: 2 years ago 2 years ago

1. lgbasallote

is this a test?

2. amistre64

is it a newtonian or non-newtonian volume?

3. amistre64

are we rotating it thru 3d or a greater dimension (4,5,6d) ??

4. lgbasallote

is it not just cylindrical shell or soemthing? am i missing soemthing?

5. satellite73

i always hated these just saying

Find the volume by slicing. For some reason the visual is hard for me to visualize.

8. lgbasallote

hmm.. i knew there was something more....

9. lgbasallote

a mod's question is never easy.....

Cant we just do translation |dw:1351171080137:dw|

12. amistre64

pi(R^2-r^2) * height (from 0 to 2 is all the same R,rs) from 2 to 4 R is still 3 but r = x

13. amistre64

$\int_{h=0}^{h=2}\pi(3^2-1^2)dh+\int_{h=2}^{h=4}\pi(3^2-(h-1)^2)dh$

14. phi

a cylindrical shell approach makes sense for this problem |dw:1351171541916:dw|

man who said art was dead? look at these pictures!

Omg. Great. @amistre64 I see it now. Thanks.
