What additional piece of information must be known in order to calculate the volume of the cylinder below?

djyliett [7]

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

$V = \pi * r ^ 2 * h$

Where:

r: It is the radius of the cylinder

h: It is the height of the cylinder

We have as data, observing the figure, that they give us the radio. Then, the height is missing.

Answer:

Option B

This is the graph of f(x). What is the value of f(3)

zubka84 [21]

Answer:

exponential function, cool

Step-by-step explanation:

looks like f(x) = e ^x

So f(3) would be e^(3)

you can work this out on your calculator.

press [2ndf] [e^x]] [3] = 20

Best thing is draw a line up from x-axis to the curve, where it hits the curve you will have your answer

Decide whether the pair of lines is parallel, perpendicular, or neither.

maw [93]

The lines are: B) Perpendicular

Step-by-step explanation:

we have to convert both lines in slope-intercept form to find slopes

So,

$3x - 6y = -13\\-6y = -3x-13\\\frac{-6y}{-6} = \frac{-3x-13}{-6}\\\frac{-6y}{-6} = \frac{-3x}{-6}+\frac{-13}{-6}\\y = \frac{1}{2} +\frac{13}{6}$

Let m1 be the slope of first line

$m_1 = \frac{1}{2}$

For the second line:

$18x + 9y = 5\\9y = -18x+5\\\frac{9y}{9} = \frac{-18x+5}{9}\\\frac{9y}{9} = \frac{-18}{9}x+\frac{5}{9}\\y = -2x+\frac{5}{9}$

Let m2 be the slope of line 2

So,

If the lines are parallel, their slopes are equal

If the lines are perpendicular, product of their slopes is -1

We can see that

$\frac{1}{2} * -2 = -1$

Hence,

The lines are: B) Perpendicular
