A bicycle wheel makes 5000 revolutions in moving 11 km. Then the radius of the wheel (in cm) is :
Correct Answer: Description for Correct answer:
Let the radius of wheel = r cm
According to question,
Circumference of wheel (2\( \large \pi \)r) x number of revolutions = 1 km
2 x \( \Large \frac{22}{7} \) x r x 5000 = 11 x 1000 x 100
r = \( \Large \frac{7 \times 11 \times 1000 \times 100}{2 \times 22 \times 5000} \) = 35cm
