Your answer is C. All you do is multiply the two answers together, in each choice. Don't let A fool you. A negative times a negative is a positive, which would make the answer incorrect.

If r= 9 units and x = 4 units, then what is the volume of the cylinder shown above?

Thepotemich [5.8K]

Answer:

Volume of the cylinder is. 1017.36

Step-by-step explanation:

$V=\pi r^2h$ is the area of a cylinder.

Let's plug in our values.

-----

3.14 = pi

9 = radius

x = height

-----

V = (3.14)(9)^2(4)

V = (3.14)(81)(4)

V = (3.14)(324)

V = 1017.36

The points (-1.6, 2.7) and (3.2, 7.98) are on the graph of a linear relationship between two variables, r and y.

Aleksandr [31]

Answer:

y = 1.1x +4.46

y = 129.86 for x = 114

Step-by-step explanation:

The two-point form of the the equation for a line is useful for this.

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

y = (7.98 -2.7)/(3.2 -(-1.6))(x -(-1.6)) + 2.7

y = 5.28/4.8(x +1.6) + 2.7

y = 1.1x +1.76 +2.7

y = 1.1x +4.46

When x=114, the value of y is ...

y = 1.1(114) +4.46

y = 129.86

A car traveld 32 miles in 4 hours at this rate how many miles will the car travel in 0.5 hours

Mandarinka [93]

Answer:

4 miles

Step-by-step explanation:

In order to find how many miles the car will travel in 0.5 hours, we can set up a proportion.

$\frac{32}{4} = \frac{x}{0.5}$

We can now cross multiply to find the value of x.

$32 \cdot 0.5 = 16\\\\16\div4 = 4$

So the car can travel 4 miles in 0.5 hours.

Hope this helped!
