The diameter of a wheel of cycle is 21 cm. It moves slowly along a road. How far will it go in 500 revolutions?  Choose the correct choice from the following answers
A) 260 m	B) 290 m	C) 320 m	D) 330 m	E) 380 m
In revolution, distance that wheel covers = circumference of wheel 330 miameter of wheel = 21 cm   Therefore, circumference of wheel = πd   = 22/7 × 21   = 66 cm   So, in 1 revolution distance covered = 66 cm   In 500 revolution distance covered = 66 × 500 cm   = 33000 cm   = 33000/100=
