Answer:
Answer: C) 400
Number of rods = (0. 88×500011) = 400.
Step-by-step explanation:
Explanation:
Given length of iron rod =7 mts and and diameter of rod = 2 cms
=> r = 1/100 mts
Therefore, Volume of one rod = πr2h cu. m = (227×[1100]2×7)cu. m = 115000 cu. m
Given volume of iron = 0.88 cu. m
Therefore, Number of rods = (0.88×500011) = 400.
