[Directly] proportional quantities.
Proportional
A relationship between two quantities where the rate of change or the ratio of one quantity to the other is constant is known as a direct proportion. In this scenario, as one quantity increases or decreases, the other quantity changes at a consistent rate, maintaining a fixed ratio. For example, if you have a constant speed while traveling, the distance covered is directly proportional to the time spent traveling. This relationship can be expressed mathematically as ( y = kx ), where ( k ) is the constant of proportionality.
Rate
The diameter and circumference of a circle.
A rate is the ratio of both those quantities.

The answer is proportional.
Two quantities are said to be proportional if they vary in such a way that one of the quantities is a constant multiple of the other, or equivalently if they have a constant ratio.
