melanie made a circular necklace. she puts bead evenly spaced around the necklace. if the 4th bead directly across from 11th head, how many beads are on the necklace on the necklace?

lo ; )

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

put in or use mine

what statement? is there an image?
