Answer:
14,660.77 ft^3
Step-by-step explanation:
The volume of a hemisphere-topped cylinder is given by the formula ...
V = πr^2(2/3r +h)
where r is the radius and h is the height of the cylindrical section. Of course, the radius is half the diameter, so this silo has a volume of ...
V = π(10 ft)^2(20/3 +40 ft) = 14,660.77 ft^3
__
Additional comment
The volume is 14,653.33 ft^3 if you use 3.14 for π.
