The diameter of cycle wheel is 28 cm. How many revolution will it make in moving 13.2 km ?

Answer»

Distance traveled by the wheel is one revolution = 2πr

=2 x 22/7 x 28/2=88 cm

and the total distance covered by the wheel = 13.2 × 1000 × 100 cm

= 1320000 cm

So, Number of revolution made by the wheel = 1320000/88

= 15000.
