Acircle is cut from a square piece of cloth, as shown: how many square inches of cloth are cut from the square? (5 points) (π = 3.14)

The number of square inches of cloth cut from the square is

(3.14) x (the diameter of the circle, in inches)² .

You've given us NO information that we can use to calculate the diameter of the circle, so that's as close as we can get.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
