C=2pi(r)
Circumference of inner circle would be C= 2(3.14)(62.5) ---> 62.5 is the radius/half the diameter given.
C1=392.5 ----> for inner circle
For outer circle, C=2(3.14)(64) ---> radius of outer circle can be found by adding the 3 feet width of the path to the inner circle diameter because that is how much wider the outer circle is, then divide by 2 for the radius
C2=401.92 ---> for outer circle
Subtract C2-C1= 9.42 feet more
