The diameter of a wheel is 0.7 m. How far will it travel in 200 revolutions

A. 4.4 m

B. 220 m

C. 440 m

D. None of These

Answer: Option C

Solution(By Examveda Team)

Diameter(d) = 0.7 m
Circumference of the wheel,
= 2 * pi *R = d * pi
= 0.7 * 3.14 = 2.198 m.
In one revolution, wheel will covered = 2.198 m,
So, in 200 revolution, it will cover = 200 *2.198 = 4.396 m = 440 m (Approx).
