Mactracker is an incredibly useful database of all Macintosh computers, and includes information about 64-bit support as well.
You can even search by model identifier (imac11,2
).
(64-bit support is first tab, second section, second line, second column)
Here's the command-line way to check on 64-bit capability, thanks to osxdaily.
$ sysctl hw | grep 64bit
hw.cpu64bit_capable: 1
First google result for imac11 was this, which says it's 2010 (only the first gen of intel were 32bit), says its i3 (all iN are 64bit), and the more detailed page of the main link says the architecture is 64bit.
If you take your processor (which you can find on the spec page for your iMac) over to Intel's site, you can look up whether it is 64-bit or not. The added bonus is that it's authoritative.

All recent Macs are 64-bit but since you wanted to prove it.
Note that to exploit all those bits, your OS and applications should also be 64-bit. There are many depends to that statement but I didn't want to write more than a sentence since it wasn't your question.
p.s. I don't have enough points to also post the link to apples spec page but according to it, you have one of these processors.
3.06GHz Intel Core i3 3.2GHz Intel Core i3 2.8GHz Intel Core i5 (quad core)
If you look under Specifications under Getting Answers in your User Guide, you'll get the link.
