Question

An old fashioned corn silo can hold 85% of its total volume. How many cubic yards of corn can a silo hold, if it has the dimensions of the figure below? Round your answer to the nearest hundredth.

Cylinder = 12ft x 21ft

Cone = 12ft x 4ft

Answer 1

Volume of cylinder = π·r²·h = π·12²·21 = _______ ft³

Volume of cone = π·r²·h/3 = π·12²·4/3 = _________ ft³

Total Volume = Volume of cylinder + Volume of cone = _______ ft³

Amount of corn it can hold = 0.85·(Total Volume) = ______ ft³
