A bicycle wheel has a radius of 35cm . What distance in kilometer does the wheel cover after 100 revolutions

A: 0.21994 cm

B: 2.994 km

C: 0.22994 km

D: 0.21994 km

Correct Answer : D

We can first convert the radius from cm to km by dividing by 100000 since

100,000 cm = 1km

35 cm = ?

(1 * 35) / 100,000

Radius in km = 0.00035

Circumference=2πr

2×0.00035×22/7

C = 2.2×10^-3

C = 0.0021994 km

1 revolution = 0.0021994km

100 revolutions = ?

(100 * 0.0021994) /1

= 0.21994 km
