I think it is 123 meters Answer:
Step-by-step explanation:
There are 2pi radians in circle
so
circumference times arcinradians/2pi=areclength
c=2pir
c=2pi25
c=50pi
arc in radians=7pi/5
c times arcrad/2pi=
50pi times (7pi/5)/2pi=
50pi times 7/10=
35pi
it is 35pi cm or aprox 109.95574287564276334619251841478 cm
Here, p^ = (0.39 + 0.47)/2 = 0.43
The given interval is (0.43 - 0.04, 0.43 + 0.04).
Therefore, the margin of error is 0.04.
