Question

(iii) A tin maker bought a sheet of tin of the length 440 m
and width 1.16 m. He made cylindrical tins closed on both
the sides of height 20 cm and radius 7 cm. While making
each tin 88 cm2 sheet is wasted, then how many tins can
be made from that sheet? PLZ GIVE ME THE ANSWER ITS 10STD MATHS PLZ​

Answer 1

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?
