The diameter and circumference of a circle.
Direct variation.
In mathematics, two quantities are proportional if they vary in such a way that one of them is a constant multiple of the other.
In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities.
ratio
The ratio between two different quantities is the rate.Usually, the second unit is a measure of time.
Proportional
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.
It is a direct proportion.
The corresponding sides of similar solids have a constant ratio.
Two variables whose ratio is constant have a linear relationship. The first variable is the second multiplied by the constant.
Direct variation.
