The calculated total distance walked by Ric is 125.6 miles
How far has he walked in miles
From the question, we have the following parameters that can be used in our computation:
The circular path (see attachment)
Where, we have
Diameter, d = 10 miles
Number of times, n = 4
The distance walked is calculated as
Distance = πd * n
So, we have
Distance = 3.14 * 10 * 4
Evaluate
Distance = 125.6
Hence, he walked 125.6 miles
