Find the perimeter of a semicircular region with a straight side that is 8 yards long. Round to the nearest hundredth if necessary

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
