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.

Six hundred paving stones were examined for cracks, and 15 were found to be cracked. The same 600 stones were then examined for

9966 [12]

Answer: 0.01

Step-by-step explanation:

Let the events are :

C = paving stones found to be cracked.

D = paving stones found to be discolored.

Given : Total stones : T = 600 (i)

C = 15

D= 27

C'∩D'= 564 (ii)

Since C'∩D' = (C∪D)' = T- C∪D (iii)

From (i) , (ii)and (ii) , we have

564 = 600- C∪D

⇒ C∪D=600- 564= 36

Formula : C∩D= C+D- C∪D

Put values , we get

C∩D= 15+27-36=6

Now ,

$P(C\cap D)=\dfrac{C\cap D}{T}=\dfrac{6}{600}=0.01$

The probability that it is both cracked and distorted is 0.01.

Part I: Describe the center and radius of the circle.

trasher [3.6K]

Answer:

Center (2,4) , radius=3, h=2 v=4 & r=3

Step-by-step explanation:

Ok so in order to find the center of the circle, use the graph (like you can see that the x is 2,if you count down from 5 to the left. the y is 4,because it's below 5 in the y pole).So the center is (2,4)

Now, in order to find the length of the radius, you need to do the following:

Take the center point (2,4) and the point where the circle ends (2,1) . Because radius is a straight, you can substract the y values of the two points : 4-1=3

As you can see in the equation, the h symbolizes the x of the center point and the v symbolizes the y.The r is the radius that we already found(3)

So it's shouldn't be a problem now to find the equation of the circle,simply replace the values with their numbers:

(x-2)^2 + (y-4)^2 = 9
