A wheel completes 1000 full rotations while traveling a distance of 88 kilometers. What is the diameter of the wheel?

Explanation

Given the wheel makes 1000 revolutions covering 88 km, the circumference per revolution is 88 km ÷ 1000 = 0.088 km (or 88 meters). Using the circumference formula C = π × diameter, diameter = circumference ÷ π = 88 ÷ 3.14 ≈ 28 meters.
