Answer 2

Given: radius of wheel = 35 cm

To find: distance travelled when the wheel revolves 5 times

Solution: When the wheel revolves, it covers the distance equal to the circumference of a circle.

The formula of the circumference of a circle = 2$\pi$r (where r is the radius of the circle)

Hence, circumference of the wheel = 2$\pi$ X 35 cm

                                                            = 219.91 cm

Therefore, total distance travelled by the bicycle when the wheel revolves 5 times = 5 X 219.91 cm

          = 1099.55 cm
