A [directly] proportional relationship between two variables, X and Y implies thatY = cX where c is the constant of proportionality.

The area of a circle is directly proportional to the square of its radius. If two circles have radii R1 and R2 , then the ratio of their areas is ( R1/R2 )2
Whatever the ratio of perimeters of the similar figures, the areas will be in the ratios squared. Examples: * if the figures have perimeters in a ratio of 1:2, their areas will have a ratio of 1²:2² = 1:4. * If the figures have perimeters in a ratio of 2:3, their areas will have a ratio of 2²:3² = 4:9.
No itβs not a factor
It is an identity.
There is no direct relationship. The perimeter is proportional to the length of the side (if you increase the side by a factor of 10, the perimeter will also increase by a factor of 10); the area is proportional to the square of the side length (if you increase the length of a side by a factor of 10, the area will increase by a factor of 100).If you know the perimeter, divide it by 4 and then square the result, to get the area (A = (P/4)2); if you know the area, take the square root and then multiply by 4 to get the perimeter (P = root(A) x 4).There is no direct relationship.

It is: 1 2 and 8
Proportional
1) It has to go through the origin (0,0). 2) It has to be consistent.
thrust and pressure are dirrectly proportional 2 each other frm d formula pressure =perpendicular force /area

I would let "direct" mean "linear." The answer then becomes simpler; direct proportional may mean a relationship like 1-1, 2-2, 3-3, etcetera. Proportional by itself would then be free to indicate other proportions; like 1-1, 2-4, 3-9, etcetera -- in an exponential proportion.
They are proportional if a change in one of the quantities always and necessarily results in a proportional change in the other.So if you think of a simple equation, x = 2y then the quantities are proportional. If you double y then x is necessarily also doubled. If you triple y then x is also tripled. If you halve y then x is halved and so forth.However x = 2y + 1 is non proportional. This is because if, for example, you double y then x is increased but it is not exactly doubled and so the change is not in proportion. For example, in this equation, when y = 2 then x = 5. When y = 4 then x = 9. 9 is not the double of 5.
The gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Time = distance3/2Kepler's 3rd Law of Planetary Motion gives this relationship:The cube of the average distance from the Sun is proportional to the square ofthe period of revolution (year).So: (Distance)3 is proportional to (year)2
A ratio between two (usually) different quantities is the rate. Usually used to describe something compared to a quantity of time.
1.) in conventional solenoid , the force is not costant...wheras in proportional .it is. 2.) proportional valve fills the gap between conventional and servo valves 3.) proportional valve can take infinite spool positions 4.)proportional valve cannot take high degree if valve performance
