The volume of a cylinder is given by the formula V = πr^2h, where r is the radius (half the diameter) and h is the height.
In this case, the diameter is 8 cm, so the radius is 8/2 = 4 cm. The height is 30 cm.
The volume of each rod is V = π(4^2)(30) = 480π cm^3.
The company uses 94,953.6 cm^3 of steel each hour.
To find out how many rods the company makes in an hour, we divide the total volume used by the volume of each rod.
Number of rods = (94,953.6 cm^3) / (480π cm^3) ≈ 63.08 rods.
Rounding to the nearest hundredth, the company makes about 63.08 rods each hour.
A company makes steel rods shaped like cylinders. Each rod has a diameter of
8
centimeters and a height of
30
centimeters. The company uses, on average,
94,953.6cm^3
of steel each hour to make these rods. How many rods does the company make, on average, each hour?
For your calculations, do not round any intermediate steps, and use the
π
button on the ALEKS calculator. Round your answer to the nearest hundredth.
