The circle is 5.1 cm what is the diameter and radius of the circle

Step-by-step explanation:

C=2πr

5.1cm=2×3.14×r

5.1cm=6.28r

r=0.8cm

d=0.8cm×2

d=1.6cm

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
