Mensuration · Question 9 · Medium
A wheel of radius 35 cm rolls without slipping. How many complete revolutions does it make in covering 1.1 km? (Use π = 22/7)
- 250
- 5,000
- 1,000
- 500
Answer and explanation
Answer: D. 500
Explanation: Circumference = 2 × 22/7 × 35 = 220 cm. 1.1 km = 1,10,000 cm, so revolutions = 1,10,000 ÷ 220 = 500.
