Question

A tin maker bought a sheet of tin of the length 4.40 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?​

Answer 1

Step-by-step explanation:

As per question the length of sheet is 4.40 m = 440 cm, and the width is 1.16 m = 116 cm, Radius = 7 cm , & Height = 20 cm

So the area of given size sheet will be = length x width

                                                                = 440 x 116

                                                                = 51040

Now the area of sheet required for making one tin = +

    =

    = 880 + 308

    = 1188

Now according to question 88 sheet is wasted in making one tin,

So the totatl area of sheet required to make one tin = 1188 + 88

                                                                                      = 1276

So the number of tin which can be made from the given sheet =

              =

              = 40 (Ans)
