Find the volume of the prism <br>pls!! show how you got the volume

mestny [16]

Answer:

Step-by-step explanation:

The way you can solve this is by splitting the cube into two parts.

Split the top cube apart from the bottom cube and then find the volume of each and add them together.

The first cube on top would be 80x90x75= 540000 centimeters

The second cube would be 270x75x80=1620000 centimeters

540000+1620000=2160000 centimeters

Hope this help!

Comment if you would like a visual drawing of the math!!

(Also the answer can be written as 21600 meters)

A 12 cm x 2 cm rectangle sits inside a circle with radius of 8 cm.

hammer [34]

Answer:

Diagram was not given.

Still I had drawn it, hope may it will helpful to you. So as per my diagram I had solved the sum.

The area of the shaded region is 176.96 ≈ 178 cm²

Step-by-step explanation:

Given:

radius of the circle = r = 8 cm

length of the rectangle = L = 12 cm

breadth of the rectangle = B = 2 cm

To Find:

Area of shaded region = ?

Solution:

$\textrm{Area of rectangle} = Length\times Breadth\\= L\times B\\= 12\times 2\\= 24\ cm^{2}$

$\textrm{Area of Circle} = \pi \times (radius)^{2} \\=\pi \times r^{2}\\=3.14\times 8^{2}\\=200.96\ cm^{2}$

Now, The Area of Shaded region will be

$\textrm{Area of Shaded region}=\textrm{Area of Circle}-\textrm{Area of Rectangle}\\=200.96 - 24\\=176.96\ cm^{2} \\=178\ cm^{2}\........... \textrm{Rounded to tenth}$

The area of the shaded region is 176.96 ≈ 178 cm²

Is the following sequence arithmetic? If so, what is the common difference?

Vsevolod [243]

Given:

The sequence is

1, 2, 4, 8, 16, ...

To find:

Whether the given sequence is arithmetic or not. If yes, then find the common difference.

Solution:

We have,

1, 2, 4, 8, 16, ...

Difference between consecutive terms are

$d_1=a_2-a_1$

$d_1=2-1$

$d_1=1$

Similarly,

$d_2=a_3-a_2$

$d_2=4-2$

$d_2=2$

Since, $d_1\neq d_2$ , therefore the given sequence have no common difference between consecutive terms.

So, the given sequence is not arithmetic.

Therefore, the correct option is c.
