Comparing and extending ratios
pam and her brother have a pattern to saving money. pam has saved $40 and her brother has saved $100. pam says that this means that for every $2 she saves, her brother saves $5. is she correct?

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
