There's no dirt in a hole.
32 cubic feet
The answer will depend on how long the hole is. The hole has 3 dimensions that determine its volume. You have provided measurements of only two dimensions.
To find the Volume: (1) find the flat area (A = Pi*R²), (2) multiply the Area by the Depth/Height (V = AD). To find how much water the vessel will hold: water = 231 cu inches per gallon, or 7.481 gal per cu ft.

A hole with two dimensions has no third dimension. → its volume is 6 ft × 10 in × 0 ft = 0 ft³ → You require NO concrete to fill a hole which is given as an area as it has NO volume.
there isn't any soil, a hole is a hole. if it had soil in it, it wouldn't be a hole would it.
A cylindrical tank 9 ft in diameter and 100 ft tall will hold ~190,418 gallons.
