Question

    What distance will a wheel with a radius of 14 cm cover

    after completing 10 revolutions?
    A 910 cm Correct Answer Incorrect Answer
    B 880 cm Correct Answer Incorrect Answer
    C 800 cm Correct Answer Incorrect Answer
    D 820 cm Correct Answer Incorrect Answer

    Solution

    We know that, circumference of circle = 2π X radius Now, Distance covered by the wheel in 1 revolution = Circumference of the wheel = {2 X (22/7) X 14} = 88 cm So, in 10 revolution the wheel will cover = 88 X 10 = 880 cm
