I can't do that fancy math.
But as a retired mason contractor...I can use a concrete calculating slide
rule.
(The redimix outfits used to hand them out free and you may ask your
supplier, they may give you one)
But...
having said that,
My calculator says that a 2"6" diameter pier, 5' deep would be 1 1/4 yards.

(we used to figure, 6 wheelbarrows to a yard for how much pushing would be
required)

There are 27 cu ft in 1 cu yd (3 ft x 3 ft x 3 ft)...so 2.5 ft x 2.5 ft x
5.0 ft = 31.25 cu ft... divided by 27 cu ft = 1.157 cu yd.  Jerry K3BZ

  Hold on here. Isn't the formula pi*r^2*h=v? My calc says about 78.5 cu ft
  or 2.9 cu yds.

  Oh, I'm sorry. I just noticed the @stanford.edu.
