Question

3. The diameter of a bicycle wheel is 42 cm. Ex amil a a) Find the distance covered in one rotation of the wheel. 22 b) What is the distance covered in 300 rotations? Give your answers in metres​

Answer 1

Answer:

If the diameter of a bicycle wheel is 42 cm then the distance covered in one rotation of the wheel 132 cm and the  distance covered in 300 rotations is 396 m .

Step-by-step explanation:

Given : diameter (d) = 42 cm

The distance covered in one rotation of the wheel = circumferance of circle

$= \pi d$

$= \frac{22}{7} \times 42$

$= 22 \times 6$

$= 132 cm$

The distance covered in 300 rotations $= 300 \times 132$

= 39600 cm

= 396 m
