    Answer:

    Number of revolution made by tire is 1.57 x 10⁷

    Explanation:

    Radius of tire, r = 0.220 m

    Circumference of tire, C = 2πr

    Substitute the value of r in the above equation.

    C = 2 x π x 0.220 m = 1.38 m

    Total distance covered by tire in a year, D = 13500 miles

    But 1 mile = 1609.34 m

    So, D = 13500 x 1609.34 m

    Number of revolutions take by tire, N = \frac{D}{C}

    N=\frac{13500\times1609.34}{1.38}

    N = 15743543
