Answer:
The equation in standard form that models area of pumpkins is:

and the area is: 
Step-by-step explanation:
Given that the garden has corn and pumpkins
The expressions are:
Total area of garden: 
Area of Corn: 
Area of Pumpkins: 
The sum of areas of corn and pumpkins is the total area of the garden.
It can be expressed mathematically as:

If we have to find the area of pumpkins,

Putting the values

The equation in standard form that models area of pumpkins is:

and the area is: 
X could either be 4 or 5, depending on which x the question asks. If you have to chose one answer go with 5 because it's associated with the y.
She will need 2.5 quarts.
For this case, the surface area of the cylinder is given by:
A = 2 * pi * r * h + 2 * pi * r ^ 2
Where.
r: cylinder radius
h: cylinder height
Substituting values we have:
A = 2 * 3.14 * 5 * (2 * 5) + 2 * 3.14 * 5 ^ 2
A = 471
Answer:
The total surface area of the cylinder is:
A = 471
