Hello!

We need to find the height of the kite in order to find the volume. We are given the surface area, which is the area of each face added up. As you can see, we can see, based on our given information, we have 1800 with the top and bottom. We can write an equation to solve below.

1800+60h+60h=7200

1800+120h=7200

Now we solve. First we subtract 1800 from both sides.

120h=5400

Divide both sides by 120.

h=45

Just to make sure, we will plug our height into the equation to make sure it is true.

1800+2700+2700=7200

Now we just multiply our base by height.

900(45)=40,500

Therefore, the volume is 40,500 cm³.

I hope this helps!

Help me with khan geometry. (Explain or give answer no link to answer thx)

NikAS [45]

Answer:

$\boxed{\sf 200\pi}$

Step-by-step explanation:

We know that the volume of a cone:-

$\boxed{\sf \pi r^2\cfrac{h}{3}}$

(r = 10) (h = 6)

$\sf \pi \times 10^2\times\cfrac{6}{3}$

<u>Divide numbers:-</u>

$\sf \cfrac{6}{3}=\boxed{2}$

$\sf 10^2\times \:2\pi$

$\sf 100\times \:2\pi$

<u>Multiply numbers:-</u>

$\boxed{\sf 200\pi}$

Therefore, your answer is 200π³

We could also multiply 200 by 3.14 which will give you 628 units³.

How many faces does this shape have?

Veseljchak [2.6K]

DO NOT LISTEN TO THE OTHER PERSON, you can CLEARLY see thats not the right answer. She/He is bluffing.

The true answer:
The shape has 4 faces. Faces means the sides of a 3d figure/the sides are the 2d shapes that form together to form one 3d figure. Btw that figure is a triangular pyramid.
Com.ment me if u have any questions

Have a nice day!

So confused some one help

SOVA2 [1]

Answer:

-2 (filled in circle) to 7 (open circle)

Step-by-step explanation:

for the first equation x must be the equal to or smaller than 6. so -3(-2) equals 6 but anything less than -2, let's say -3(-3), will be BIGGER than six, so -2 including -2 which is a filled in circle.

solving it:

-3(x) $\leq$ 6

$\frac{-3x}{-3} \leq \frac{6}{-3}$

$x\leq -2$

for the second equation x must be smaller than 17. so first you take out + 3 by subtracting it, leaving the equation as 2x<14. 2(7)<14 is NOT true so anything bigger than 7 leaves it as true because 6.98934747483 can still make it true, so anything smaller than 7 which is 7 with a not filled in, or open, circle

solving it:

$2x + 3 (- 3) < 17 (- 3)$

2x < 14

$\frac{2x}{2}$

x < 7

my explanation is all over the place, but hope this helps!!!

Answer:

x^2+x + 1/4

Step-by-step explanation:

x^2+x

Take the coefficient of x

divide by 2

1/2

Square it

(1/2)^2 = 1/4

Add this to make a perfect square trinomial
