The diameter of a wheel is 63 cms. Distance travelled by the wheel in 100 revolutions is ?
-
- 99 meters
- 198 meters
- 63 meters
- 136 meters
Correct Option: B
Distance travelled in 1 revolution = circumference of the wheel
= πd
= ( 22/7 ) x 63
= 198 cm
So the distance travelled in 100 revolutions = 100 x distance travelled in 1 revolution
= 100 x 198 cm
= 19800 cm
= 198 m
