Answer:
circumference of circle =2 pie r
radius=19cm
now,
2pie r=2×22/7×19cm
=119.4285714
To answer this question you basically have to add up day 1, day 2 and day three then take it away from 30 so.....
7.7+6.4+8.0=22.1
30-22.1=7.9 so they have 7.9 miles left to walk
40
Times 1.1 is also my best answer it’s a guess in between
The radius is <span>24.5
R = C/2pi
