A grain silo is built from two right circular cones and a right circular cylinder with internal measurements represented by the figure above. What is the volume of the grain silo, in cubic feet?
Vsilo = 2Vcone + Vcyl
Vcone = (πr2hcone)/3 = 125π/3
Vcyl = πr2hcyl = 250π
Vsilo = 2(125π/3) + 250π = 1000π/3 ft3
Given only 1 significant digit, the volume of the silo is 1000 cubic feet.
