the expression for a proportional relationship is,
![y=kx](https://tex.z-dn.net/?f=y%3Dkx)
here, k = proportionality constant
we will put the value of x and y corresponding to each other from the table
for (3,18)
![\begin{gathered} 18=k\times3 \\ k=\frac{18}{3} \\ k=6 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%2018%3Dk%5Ctimes3%20%5C%5C%20k%3D%5Cfrac%7B18%7D%7B3%7D%20%5C%5C%20k%3D6%20%5Cend%7Bgathered%7D)
for (6,36)
![\begin{gathered} 36=k\times6 \\ k=\frac{36}{6} \\ k=6 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%2036%3Dk%5Ctimes6%20%5C%5C%20k%3D%5Cfrac%7B36%7D%7B6%7D%20%5C%5C%20k%3D6%20%5Cend%7Bgathered%7D)
thus the given table is the table of a proportional function
and the constant of proportionality is 6
ANSWER : A= 3r^2 {r<u>></u>0}
1. square both sides
2. Expand
3. solve 3^2= A/3 : A= 3r^2
4. A=3r^2
5. Verify solutions
