The equation for circumstance is 2πr and one tire is 62.83 so two tiers would be 125.66 or ≈ 120

Answer: 120 in.
Step-by-step explanation:
Given : Jim has 20-inch wheels on his bicycle (their diameter is 20 inches).
Then, the radius of the tire = [tex]\dfrac{20}{2}=10\ in.[/tex]
Now, the length of rubber we got from each tire is given by Circumference.
Circumference of a circle is given by :-
[tex]C=2\pi r=2(3.14)(10)=62.8\text{ in.}[/tex]
i.e. the length of rubber we got from each tire is 62.8 inches.
Now , the length of rubber Jim would get from his two bicycle tires :-
[tex]2\times64.8=125.6\approx120\text{ in.}[/tex]
Hence, the estimated length of rubber Jim would get from his two bicycle tires. = 120 in.
