If volume is the relevant thing, yes.

As a practical matter, the holes I've seen drilled have always been much 
deeper than in diameter.  In your example, perhaps 3 ft in diameter by 
13 feet deep, or 2.5 ft by 19-20 ft.

An interesting question.. what if you were just to drill/dig a 2 foot 
diameter hole and bury some length of tower segments, in either dirt or 
concrete?  If you do it like telephone poles, they bury 15-20% of the 
overall length and they do it in plain old dirt.
