First, find the circumference of the tire to estimate the length of chain that is needed.
The wheel tire takes the shape of a circle, hence use the formula for the circumferece of a circle:
[tex]C=2\pi r[/tex]
Substitute r=1.5 into the formula and use π=22/7:
[tex]\begin{gathered} C=2\times\frac{22}{7}\times1.5 \\ \approx9.43\text{ ft} \end{gathered}[/tex]
Notice that the circumference of the wheel is about 9.43ft which is more than 6ft. Hence, a 6ft long chain will not be enough to surround the wheel tire.
