To determine how many revolutions wheel A makes when wheel C completes 16 revolutions, it is essential to understand the relationship between the radii of the wheels and how they translate to revolutions. Each wheel's circumference is directly proportional to its radius, which means that if the radius of one wheel is different from another, the number of revolutions will also change accordingly.

If wheel C is making 16 revolutions, the distance it covers can be calculated based on its circumference, which is proportional to its radius. When this distance is applied to wheel A, which has a different radius, it will complete a different number of revolutions depending on how much of that distance aligns with the circumference of wheel A.

In this scenario, if the analysis shows that wheel A has a radius that allows it to complete 4 times more revolutions than wheel C for the same distance covered, then for each revolution wheel C makes, wheel A completes 4 revolutions. Therefore, when wheel C completes 16 revolutions, wheel A would complete 4 times that amount, resulting in 64 revolutions. However, the question asks for the number of revolutions of wheel A in relation to wheel C completing 16 revolutions, indicating a simpler ratio
