At his trucking company, Steve received an order to ship 321 cubic feet of oil in cylindrical steel barrels. If each barrel has a radius of 1.6 feet and is 4.9 feet tall, how many steel barrels will Steve need?

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

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.
