Which statement is true about the given function?

it's the 3rd option

Step-by-step explanation:

f(x) 0 over the intervals (–∞ –3)

Hope it's right

For this case we have that by definition, the volume of a cylinder is given by:

Where:

r: It's the radio

h: It's the height

We have as data that the volume of the cylinder is:

They also tell us that the height is "x", then:

We have similar terms on both sides of the equation:

We apply root to both sides of the equation:

We choose the positive value. Now the radio is 2x
