A silo is in the shape of a cone. The silo is
9
meters tall, and its base has a radius of
2
meters. Wheat costs
$232
per cubic meter. How much will it cost to fill the silo with wheat?

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 -----
