Circumference of the wheel= 1 revolution
22/7 X 21 = 66cm
66 X 15 = 990cm
990 X 8 = 7920cm (total distance)
22/7 X 14 = 44cm ( 1 revolution) (1 smaller circle)
7920 ➗ 44 = 180 revolutions
22/7 X 21 = 66cm
66 X 15 = 990cm
990 X 8 = 7920cm (total distance)
22/7 X 14 = 44cm ( 1 revolution) (1 smaller circle)
7920 ➗ 44 = 180 revolutions
