Since we have that the volume of a sphere is given by:


V=(3)/(4)\pi r^3

And we have that the diameter equals 3.6ft, we then will have a volume of:


V=(3)/(4)\pi(1.8)^3\Rightarrow V\approx13.74

Since we have that the volume is approximately 13.74 ft^3, then the best approximation in the problem is A. 13.6 ft^3.
