Answer:
42.5miles
Step-by-step explanation:
68÷8= 8.5
8.5×5= 42.5 miles
we use the numbers given to us because we are finding the estimate.
our estimate is correct because 68km= 42.3 miles
Circumference = 2Pi(r) = 6Pi
angle of arc s = 360 - 106 = 254 degree
Arc length = 6Pi ( 254 ) / 360 = 4.2Pi
Pi = 3.14
The answer is D. Group =2
