Question

joe cuts disc from a rectangular sheet of silver to make jewellery. the sheet is 130cm long and 70cm wide. each disk has a diameter of 6cm.


what is the maximum number of disc he can cut from the sheet. use 3.14

Answer 1

the sheet is (140/6) by (70/6) = 23.3 by 11.7 discs in size
That is, it is basically 23x11 discs.
How many is that? No pi involved here.

Actually, depending on how he cuts the discs, he can get more than this, but I suspect that packing theory is beyond the scope of this assignment.
