Lily swims a 100-meter race. She swims the first half in 27.8 seconds. She swims the second half in 30.12 seconds. About how long does it take Lily to swim the whole race? Choose the best estimate. 70 seconds 158 seconds
42 seconds 58 seconds

The answer is: 57.92 seconds

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
