Calculate the area of the largest circle that can be cut from a rectangular sheet of metal and the percent of the rectangle wasted.
Dimensions of sheet: Length- 11 in., Width- 8.5 in.
..... The diameter of the largest possible circle is the same as length of the width of the rectangle.
Calculate the area of the circle. (ANSWER 1)
Calculate the area of the rectangle.
Deduct the area of the circle from the area of the rectangle, that difference is the wasted area.
Get that wasted area in terms of a percentage of the total area of the rectangle. (ANSWER 2)
..... Good luck!
