We need to find the volume of the cone to first see how much total wheat we can fill. So,
V=(pi)r^2(h/3)
V=(pi)2^2(9/3)
V=(pi)4(3)
V=(pi)(12)
V=37.7 meters cubed.
If 1 cubic meter is equal to $232, we simply take the volume (37.7) and multiply that by the cost of 1 cubic meter ($232).
232x37.7= 8,746.40
----- It will cost $8,746.40 to fill up the silo with wheat -----
