Step-by-step explanation:
We have to find the set of value which could be from a direct proportion.
We know that
Direct proportion :
When x is directly proportional to y
Where k=Proportionality constant
K remain constant when x and y are in direct proportion
From first table
When x and y are both varies then ratio of x and y remain constant.Hence, it is in direct proportion.
From second table
not ]define
It is not direct proportion because k does not remain constant.
From third table
It is not direct proportion because k does not remain constant.

As we know that the equation for surface area of a cylinder,
Surface area of cylinder =
Where,
r - the radius of the cylinder. Here given diameter (D) as 6. So,
h - the height of the cylinder (given as 11 cm). The value for pi = 3.14. Now, calculate the surface area of the cylinder as
A = 56.52+ 207.24 = 263.76 cm
