The diameter of a wheel is 1.26 m. How far will it travel in 500 revolutions?
Answer: (a) 1980
The diameter of a wheel = 1.26 m
Then, the circumference of the wheel = 22 x 1.26/7
= 3.96 m
The number of revolutions = 500
Then, distance covered by the wheel in 500 revolution = 1980 m
Hence, the correct answer is option (a) 1980.
