Question

A bicycle makes 5000 revolution in moving 11km. find the circumference and diameter of the wheel.

Answer 1

Wheel of bicycle makes 5000 revolutions in order to cover 11 km

Wheel Bicycle will revolve only time and will cover = $\dfrac{11\:km}{5000} =\dfrac{11000\:m}{5000} = \dfrac{11}{5}\: m$

Wheel of bicycle revolves one time and cover the distance of $\dfrac{11}{5} \: m$

Therefore, Circumference of the wheel is 11 / 5 m

Circumference of wheel = 11 / 5 m

2πr = 11 / 5 m

dπ = 11 / 5 m

d × 22 / 7 = 11 / 5 m

d = 11 / 5 × 7 / 22 m

d = 7 / 10 m

d = 0.7 m

Therefore, diameter of the wheel is 0.7 m.
