Toms company supplies circular cover plates for recessed can lights. How many plates with a 1 ft radius can be made
from a 4ft by 8 ft sheet of stainless steel? What percentage of the steel will be available for recycling?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Cut // divide // separate the original 4 x 8 sheet into 2*4 = 8 squares 2 x 2 feet each and make 1 plate from every cut.


2*4 = 8 circular plates.


For recycling: 8%2A%282%5E2+-+pi%2A1%5E2%29 = 8%2A%284-pi%29 = 6.88 sq.ft.

Percentage: 6.88%2F%284%2A8%29 = 0.215 = 21.5%.

Solved.
