Question

. A bicycle wheel makes 5000 revolutions in moving 11 km. Find the circumferene
diameter of the wheel.​

Answer 1

Let the radius of the wheel be r cm.

Distance covered by the wheel in one revolution = 500011 km = 220 cm

2πr=220 

2×722×r=220

r=35 cm

Diameter = 2r=70 cm

Answer 2

Step-by-step explanation:

Let the diameter of the wheel be d m

Therefore, circumference = Pi × d m

Therefore,

As Per Question,

Pi × d × 5000 = 11000

d = 11000/5000 ×7/22 = 0.7 m = 7 cm

Circumference = 22/7 × 7 = 22cm
