To find the answer we need to find the raduis
Circumference = 2πr
r=[tex] \frac{Circumference}{2 \pi } [/tex]
r=[tex] \frac{654}{2 \pi } [/tex]
= 104.08
The diameter is 2r, hence the diameter is 208.16
If the rate to cross is 6ft. per second, time can be found by dividing the raduis by 6
It would take 34.7 seconds
