B) -8 + (-12)
Because you just have to use the distributive property and distribute -1 to (8+12)

Will mark brainliest to whoever answers correctly first!!!

To find the volume, you do area multiplied by thickness( or height)
In this example, you do (1/2*9*6)*10 which is 270
hope I helped ;)

A 540-acre piece of land is being divided into 6-acre parcels. how many parcels will there be?

ryzh [129]

Basically, what you will do is 540 divided by 6

When you divide that, you should get, 90 parcels.

Hope this helps! Have a good rest of your day! c:

Maria want to make a footstool in the shape of a cylinder, as show below. She wants to fill the footstool with foam and cover it

dexar [7]

Answer:

She'll need 8143 cubic inches of foam and 1,809.6 square inches of fabric.

Step-by-step explanation:

Assuming you want to know how much foam and fabric she will need...

First the foam... so we need to determine the volume of that footstool. The Volume of a cylinder is given by:

V = π * r² * h

So, we plug in the numbers:

V = π * 12² * 18 = π * 144 * 18

V = 2,592 π = 8143 cubic inches.

Now for the fabric... we'll assume Maria wants to cover the side of the stool and the top, but not the bottom.

The side of the stool is basically a rectangle of width of 18 inches and a length of the circumference of the base of the stool. The circumference is given by: C = 2 π * r of course, so C = 24π = 75.14 inches.

So the lateral surface of the cylinder is:

LS = 18 * 75.14 = 1,357.2 sq inches.

Then we need to calculate the area of the top... which is easy:

A = π * r² = π * 12² = 144 π = 452.4 sq inches

So, to cover the lateral side of the footstool and its top, she needs to use:

TA = 1,357.2 + 452.4 = 1,809.6 sq inches of fabric.

If r=8 and h=4, what is the volume of the cylinder shown above

Inessa05 [86]

Lets get started :)

The Volume formula of a Cylinder is
V = $\pi$ r²h
(r = radius, h = height)

The radius given is 8 and the height is 4, We can plug in the known values

V = $\pi$ (8)²(4)
= $\pi$ 256
= 256 $\pi$ units³ (You can leave the answer in this form)
≈ 804.2 units³ (approximately)

Units³ because it is a volume (3D shape)
