If you like my answer, please make me the brainliest answer! It means a lot. :)
We must remember the formulas for volume for these different shapes.
Volume of a hemisphere = \(\frac{2 \pi }{3}\)r³
V = \(\frac{6.28}{3}\)8³
V = \(\frac{6.28}{3}\)512
V = 1071.787
Volume of a cylinder = \(\pi\)r²h
V = \(\pi\)8² × 40
V = 8042.477
Volume of Silo = 1071.787 + 8042.477 = 9114.264 feet³
Volume of Rectangle = l × w × h
V = 8 × 5 × 4
V = 160 feet³
Truckloads that can fit into silo = 9114.264 ÷ 160 = 56.964 truckloads.
You can round off to whatever you need to.
