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

Distance covered in 1 rotation = circumference of the wheel

                                                  = 2r

                                                  = 2 x 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.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
