Formula for volume of a sphere is : V = 4/3 pi (r)^3
given r = 2 feet
Therefore, volume V = 4/3 pi (2)^3
= 4/3 pi 8
Substituting the value of pi (3.14)
= 4/3 x 3.14 x 8
=33.5 cubic feet

To know how the formula is derived, refer to the site above:
Formula for volume of sphere:
V = 4/3 (pi) (radius^3)
Assume pi = 3.1416
V = 4/3 (3.1416)(2^3)
V = 4/3(3.1416)(8)
V = 100.5312/3
V = 33.5104 cubic ft or
V = 33.5 ft^3
