Volume = 3ft x 3ft x 9ft = 81 cubic feet.

None. It is a hole and therefore contains nothing.
2ft x 3ft x 5ft = 30 cubic feet.
Depends on if your talking about a 'square yard' or a 'cubic yard'. A 'square yard' has 9 square feet (3ft x 3ft). A 'cubic yard' has 27 square feet (3ft x 3ft x 3ft)
Volume = 3ft x 3ft x 9ft = 81 cubic feet.
If these dimensions are in feet then the volume would be about 101 US gallons.

In the United States, if you are buying concrete mixed up and ready to pour, it is typically sold by the cubic yard (3ft x 3ft x 3ft) volume. But they usually call this just a 'yard' of concrete, knowing that it is a cubic yard.

A yard of Concrete is 3ft x 3ft x 3ft volume. It is usually poured over a 2" gravel sand mix for an additional four inches. So it should cover 36 "/4" = 9 (x 3ft x 3ft), or 81sq ft.The 'square feet' of area that it covers is 324/(depth of the concrete, in inches)
None. It is a hole and therefore contains nothing.
2ft x 3ft x 5ft = 30 cubic feet.
A cubic yard is: volume defined by a cube that is 3ft x 3ft x 3ft; i.e. 3ft high x 3ft wide x 3ft deep. For example: a box 3x3x3 feet filled with gravel is one cubic yard since a yard=3 feet.
Volume of sphere = 4/3 x (pi) x (radius)3 but radius = diameter/2 = 6ft/2 = 3ft therefore Volume= 4/3 x 3.14 x 27 = 113.04cubic feet

I presume 1 yard of mulch means 1 cu yard of mulch 1yd = 3ft 1 cu yard = 1yd x 1yd x 1yd = 3ft x 3ft x 3ft = 27 cu ft. 12 in = 1ft 1in = 1/12 ft 3in = 3/12 ft = 1/4 ft volume = area x depth => area = volume / depth = 27 cu ft / (1/4 ft) = 108 sq ft.
