Question

the diameter of bicycle wheel is 63 cm.find how many times the wheel will revolve in order to cover a distance of 99m

Answer 1

The perimeter of bicycle wheel=πd
=22/7*63
=198cm
=1.98m
99=n*1.98
99/1.98=n
n=50

Answer 2

The circumference of the circle is 198 cm by 22/7*63.

Therefore it needs to cover 1/2 revolution to cover 99 m
