The circumference of a circular painting is 21.98 feet. what is the radius of the painting? use 3.14 for π and do not round your answer.

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

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
