Since the diameter is 6 cm, the radius is 3 cm. Use the area formula to get 113.04 cm squared. Then, you multiply that by the height of the rod, which is 20 cm. The volume of one rod is 2260.8 cm cubed. To find how much steel is needed for 189 rods, multiple the volume of one rod by 189. Your answer should be 427291.2 cm³.
Answer: B. 95.0
Step-by-step explanation:
In statistics , the famous empirical rule says that " if the data is normally distributed then 68% of the observations will be contained within 
standard deviations from the arithmetic mean, 95% of the observations will be contained within 
standard deviations from the arithmetic mean and 99.7% of the observations will be contained within 
standard deviations from the arithmetic mean".
Hence, B is the correct answer.
