Question 1206476: The sketch above shows a component which is stamped out of sheet steel. The square in the center is discarded. These components are stamped out of a continuous steel coil with a width of 70 cms. The stamping process requires a gap of 25mm between each component. The steel coil is supplied in lengths of 25 meters costing $200.
1) What is the approximate area of the remaining shape in square centimetres?
A B C D E
1938 1855 1926 1880 1760
2) What is the approximate percentage of steel wasted including the center square?
A B C D E
56% 50% 62% 48% 52%
3) Assuming minimal wastage, how many components can be produced from each 25 meter coil?
A B C D E
38 40 36 42 37
4) What is the approximate cost of a component if the scrap is sold at 50% of cost?
A B C D E
$3.60 $3.15 $3.55 $5.00 $4.85
