Answer:
9 barrels
Step-by-step explanation:
The first thing is to calculate the volume of the barrel, we know that it has the shape of a cylinder, the volume of the cylinder is:
V = pi * (r ^ 2) * h
we replace r = 1.6 h = 4.9
V = 3.14 * (1.6 ^ 2) * 4.9
V = 39.39
the volume of the barrel is 39.39 ft ^ 3
To know how many are needed, we must divide 321 by the volume of the barrel, like this:
321 / 39.39 = 8.15
Which means that it needs 9 barrels to supply the demand since with 8 it is incomplete
