Question 1141391: A company makes steel rods shaped like cylinders. Each rod has a diameter of
4 centimeters and a height of 90 centimeters. If the company used 30,520.8 centimeters cube of steel, how many rods did it make?
Answer by math_helper(2461) (Show Source): You can put this solution on YOUR website!
The volume of each rod is = 1130.973 cm^3
Now divide the volume consumed by the volume of each rod:
= 26.986 (they can make , with just less than one rod's worth of material left over)
Side note: I ignored the possibility that the stock material has a shape that allows fewer rods to be made.
Be aware that sometimes the geometry given for the stock material will also come into play.
