SUMMARY
The problem involves calculating the radius of a wheel based on the distance a string is pulled and the number of revolutions made by the wheel. The key relationship is between the circumference of the wheel and the radius, where the circumference can be determined by the formula: Circumference = Length of string pulled / Number of revolutions. This relationship allows for the calculation of the radius using the formula: Radius = Circumference / (2π).
