The diameter of a wheel is 63 cms. Distance travelled by the wheel in 100 revolutions is?
Options:
A . 198 meters
B . 63 meters
C . 99 meters
D . 136 meters
Answer: Option A
Distance travelled in 1 revolution = circumference of the wheel = ?d= ( 22/7 ) x 63= 198 cmSo the distance travelled in 100 revolutions = 100 x distance travelled in 1 revolution = 100 x 198 cm= 19800 cm = 198 m
