Q. |
If the wheel of a bicycle makes 560 revolutions in travelling 1.1 km, what is its radius? |

✔ A. |
31.25 cm |

✖ B. |
37.75 cm |

✖ C. |
35.15 cm |

✖ D. |
11.25 cm |

**Solution:**

Option(**A**) is correct

The distance covered by the wheel in 560 revolutions = 1100 m.

Hence, the distance covered per revolution = \(\dfrac{1100}{560}=\dfrac{55}{28}\) metres

The distance covered in one revolution = circumference of the wheel.

Circumference \(=2\pi r=2\times \dfrac{22}{7}\times r\)

$⇒ r$ = **31.25 cm.**
