Answer:
total area of tin sheet = lb = 44000 * 1160 = 51040000 cm2
CSA of cylinder = 2 pie * r * h = 2 * 22/7 * 7 * 20 = 880 cm2
Total cylinder made = 51240000/880 = 58000 tins
Each time wasted = 58000 * 88 = 5104000 cm2
Remaining tin = 51040000 - 5104000 = 4,59,36,000 cm2
total tins made = 45936000/880 = 52200 tins
Confirm it whether is it correct?
