mrs. santiago is buying doughnuts for her office. each box contains 6 glazed, 4 cream filled, and 2 chocolate flavored doughnuts. if there were 20 total cream filled doughnuts, how many chocolate doughnuts did she buy?

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.

step-by-step explanation:
