Jerry has two same size circles divided into same number of equal parts. one circle has 3/4 of the party shaded and the other has 2/3 of the part shaded. his sister says the least number of pieces each circle could be divided into is 7. is his sister correct ? explain

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
