Which choice shows the numbers correctly ordered? Please help me I will give out extra points and the brain thing.

I think it's B

Step-by-step explanation:

square root of 1/21 is smallest, then 1/5, then 4.15, then square root of 21

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
