David's class gets 19 minutes of recess every day. In October they had 23 school days. David wants to know about how many minutes of recess they had in October.
Which is the best way to estimate the answer?

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.
