No, because one x-value corresponds to two different y-values
Answer:
<h2>x = 140, y = 80</h2>
Step-by-step explanation:

First of all, it's not pie. It's pi.
Now, the problem.
Radius is always 1/2 x d (d meaning diameter)
That gives us 5.
The formula is 3.14 x 5^2(h/3)
If you solve it from left to right, you get 130.83
<u>Part 1</u>
The value of y is twice that of x, so the equation is y = 2x.
<u>Part 2</u>
Substituting in x = 14, we get y = 2(14) = 28.
