Is this function a linear function? Yes or no y= 2x^2
2 answers:
Answer:
No
Reasoning:
There are two ways to figure this out.
1. You know when a function is linear when the equation is in the slope-intercept format. Which looks like
This does not look like that. So, it isn't a linear function.
2. Graph! If you graph the function, the graph will look like the figure below. It's not a line. This is called a parabola. Meaning, it's not a linear function.

Answer:
Volume of the tank = 636 ft³
Step-by-step explanation:
Formula for the volume of a cylinder is,
V = πr²h
Where r = radius of the cylinder
h = height of the cylinder
By substituting the values of radius and height of the water tank given in the question,
V =
= 202.5π
= 202.5 × (3.14)
= 635.85 ft³
≈ 636 ft³
Therefore, volume of the cylindrical water tank is 636 ft³.
