The volume of a sphere can be calculated using the formula V = (4/3) * π * r^3, where r is the radius of the sphere.
Since the diameter is 2 ft, the radius would be half of this, which is 1 ft.
Plugging this into the formula, we get V = (4/3) * π * 1^3 = (4/3) * π * 1 = 4.18879...
Rounding to the nearest tenth, the volume of the sphere is 4.2 ft^3.
Therefore, the correct response is A. 4.2 ft^3.
