zalisa [80]

Step-by-step explanation:

This problem bothers on the mensuration of flat shapes, a rectangle.

We know that the area of a rectangular shape is

Area =length x width

Since we don't have any specific data regarding Nathan's plot of land

Let's assume some figure for better understanding

Say the length is 18m

And the width is 12m

Area = 18*12

Area= 216m²

A dog is on a 20-foot leash in the backyard. Approximately how much area does the dog have to move around in the yard?

iragen [17]

With a 20 ft leash, the dog can move in the circle. Now, knowing that he can move around in a circle, we just need to use the circle formula. A = 3.14(r) squared.
Since you use 3.14 for pi; A = 3.14(20) squared --> A = 1256

Answer = 1256

Graph the line with slope -2 passing through the point (3,4)

Maurinko [17]

Answer: The line that contains the points A and B

Step-by-step explanation: In this problem, we're asked to graph the line that contains the point (3,4) and has a slope of -2.

We would start things off by plotting our point, (3,4).

If you need a review on plotting points, take a look below.

The first number in our point represents the x coordinate or how far we move to the left or right from the origin.

The second number in our point represents the y coordinate or how far we move up or down from the origin.

So we go over 3 units and up 4 units and call that point A.

In order to graph a line however, we need two points

and that's where our slope comes in.

Remember that slope means rise over run. So from our original point that we have already plotted, we rise -2 units and run 1 unit.

When you have a slope that's an integer like -2, just put it over 1.

After rising 2 units and running 1 unit, plot your second point

which I have plotted as point B.

You could if you wanted to continue to plot more and more points but we just need at least two points to graph a line.

So our answer is then the line that contains the points A and B.

The height of a cylinder is twice the radius of its base.

Ber [7]

Let x represent radius of circle.

We have been given that the height of a cylinder is twice the radius of its base. So height of cylinder would be $2x$ .

Now we will use volume of cylinder formula to our given problem.

$V=\pi r^2h$ , where,

r = Radius of base of cylinder,

h = Height of cylinder.

Upon substituting our given values, we will get:

$V=\pi\cdot x^2\cdot 2x$

$V=2x^3\pi$

Therefore, our required volume expression would be $2x^3\pi$ .
