Radius of circular path = distance from path to the tree in the centre
Radius of circular path = 0.75 miles
Length of path = Circumference of path(circle)
Circumference of the circular path :
[tex] = \tt2\pi r[/tex]
[tex] =\tt 2 \times 3.14 \times 0.75[/tex]
[tex] =\tt 6.28 \times 0.75[/tex]
[tex] =\tt 4.71 \: miles[/tex]
Thus, the circumference of the circular path = 4.71 miles
Therefore, the circular path is 4.71 miles long.
