Question

How many iron rods each of the length 7 m and diameter 2 cm can be made out of 88 m3 of iron

Answer 1

Answer:

Step-by-step 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.
