The formula is V=πr2h. I love querty keyboards 
V=3.14 x.75(squared) x5 or 8.8 cu ft. 15 each 80 lb bags of sackrete per hole. What volume does your rebar take up?

volume = radius squared ( that's radius multiplied by radius ) X pi ( that's 3.14159 + much more----- ) X 5',,, ea 80#b has its volume printed on it,,, i expect you'll leave more in the wheelbarrow after mixing than displaced by rebar,,, trying to be tactful here - conc's only $4 per 80#b or, in your case, roughly $53.00 - cylinder volume was 7th grade geometry in my day + its easily avail on the i-net if you use google or, probably, ANY other search engine,,, best of luck ! enjoy your day ! happy to help !

here's a site with a little script on it which will calculate yards needed to fill a particular size/shape.
conversion from yards to bags should be simpler, and will depend on how you're making your concrete.

this is such a simple calculation, it seems weird to me that some version of it isn't just printed on the sonotube itself, missed opportunity for marketing there.
