The radius of a circular wheel is 1.75 m. The number of revolutions it will make in travelling 11 km is : (use π = 22/7)
-
- 800
- 900
- 1000
- 1200
- 800
Correct Option: C
Using Rule 7,
The distance travelled by wheel in one revolution
| = 2πr = 2 × | × 1.75 m = 11 m | |
| 7 |
Therefore, the number of revolution to cover 11 km i.e. 11000 m by wheel
| = | = 1000 | |
| 11 |
