The standard length of film on a reel is 400 meters. On the first day of shooting a movie, a director uses 40% of the film on one reel. How long is the strip of film used?

240 meters all you are doing is finding 40 percent off 400

Step-by-step explanation:

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.
