The radius of a wheel is 0.25 m. How many rounds will it take to complete the distance of \( 11 k m ? \)
- A. 7000
- B. 8000
- C. 9000
- D. 6000
Step-by-step solution
Radius r = 0.25 m. Circumference = 2πr = 2 × π × 0.25 = 0.5π m. Distance = 11 km = 11000 m. Number of rounds = distance / circumference = 11000 / (0.5π) = 22000/π ≈ 7000.
