Deriving the volume of an n-ball
I undid your recent change to the Deriving the volume of an n-ball article because I believe that the formula you put in is incorrect, and that the original formula was correct. If you think I have made an error, please let's discuss it on the talk page for that article. To do that simply click on the link for that talk page and click on the tab that says "new section". You can then put in a useful section title and text explaining what you think I am doing wrong. I will watch that page for your edit. Thanks for joining Wikipedia! — Q uantling (talk &#124; contribs) 13:29, 13 June 2011 (UTC)
