**A bicycle wheel makes 5000 revolutions in moving 11km. Find diameter of wheel?**

Asked by vedantsagrawal23 | 01 Aug, 2019, 06:48: PM

Expert Answer

11km = (11 × 1000 × 100)cm

Distance covered by a Bicycle in 1 revolution = (11 × 1000 × 100) ÷ 5000 = 220 cm

Circumference of a circle = 220 cm.

→pi × d = 220

→(22/7)× d = 220

→ d = 70cm

Therefore the diameter of a wheel is 70cm.
