V=(1/3)hπr^2 where h=height and r=radius
given
radius=3
height=2a
r=3
h=2a
v=(1/3)hπr^2
v=(1/3)(2a)π(3)^2
v=(1/3)2aπ9
v=6aπ
so the expression would be some variaant of v=6aπ
Using the area of a rectangle, it is found that her patio should have a width of 12 feet and a length of 27 feet.
<h3>What is the area of a rectangle?</h3>
The area of a rectangle of length l and width w is given by:
A = lw.
In this problem:
- She has enough tiles to cover 324 square feet, hence A = 324.
- She wants the length of the patio to be 15 feet longer than the width, hence l = 15 + w.
Thus:
324 = w(15 + w)
w^2 + 15w - 324 = 0
w = -27 or w = 12.
We take the positive value, hence l = 15 + w = 15 + 12 = 27 feet.
The dimensions should be a width of 12 feet and a length of 27 feet.

Answer:
To make a table u need to have coordinates, (x, y).
Solve for them using substitution:
y = x - 4 ↔ x = y + 4
y = (2x - 17)
PLUG IN TO y = (2x - 17).
y = (2(y+4) - 17)
Solve for y:
y = 2y + 8 - 17
y = 2y - 9
-1y = -9
y = 9
Solve for x:
x = (9) + 4
x = 13
Keep solving for x and y to have your coordinates for your table.
