Question

The radius of the wheel of a bicycle is 14 inches. What is the distance that the bicycle covers after ten rotations? Use

Answer 1

Distance covered in 1 rotation = circumference of the wheel

                                                  = 2$\pi$r

                                                  = 2 x $\frac{22}{7}$ x 14

                                                  = 2 x 22 x 2

                                                  = 88 inches

Distance covered in 10 rotations = 88 x 10 = 880 inches

Therefore, the bike covers 880 inches after 10 rotations.
