Question

The diameter of a bicycle wheel is 42cm. If the wheel makes 16 complete revolution, what will be the total distance covered by the wheel? [Take \(\pi \frac{22}{7}\)

Options

A) 672cm

B) 1056cm

C) 2112cm

D) 4224cm

The correct answer is C.

Explanation:

d = 42cm

Circumference = \(\pi d = \frac{22}{7} \times 42cm\)

= 22 x 6cm = 132cm

Total distance covered = circumference x number of revolutions

= 132cm x 16 = 2112cm

  • d = 42cm

    Circumference = \(\pi d = \frac{22}{7} \times 42cm\)

    = 22 x 6cm = 132cm

    Total distance covered = circumference x number of revolutions

    = 132cm x 16 = 2112cm
