A cone has a volume of 36π ft^3. The height of the cone is 12 ft. Find the diameter of the base of the coneRound to one decimal place if necessary.

Answers

Answer 1
Answer:

Answer: 6 feet

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a cone= (1/3) π radius² height

Replacing with the values given and solving for r:

36π = (1/3) π r² 12

36π/ [(1/3) π 12]= r²  

9 = r²  

√9 =r

3 ft = r

Since:

Diameter = 2 x radius

Substituting r=3  

D = 2x 3

D = 6 feet

Feel free to ask for more if needed or if you did not understand something.

Given:- KLMN is a trapezoid
- KL = MN
- LN = √(89)
- LH: altitude
- LM = 3
- KN = 13
Find: m∠LKN
See attached image.

Answers

Answer:

45 degrees

Step-by-step explanation:

If KL = MN, and LM =3 and KN = 13, then HN = 13 - (13-3)/2 = 8

LN =  sqrt(HN^2 + LH^2) -->

LN = sqrt89 sqrt(8^2 + LH^2) -->

89 = 64 + LH ^2 -->

25 = LH^2 -->

LH = 5

Because HN  = 8, HK = 13 - 8 = 5

That makes both legs equal, which makes m∠LKN = 45 degrees

The angle  m∠LKN is equal to 45 degrees.

To understand more, check below explanation.

Trapezoid :

It is given that,

KL = MN, LM =3 , KN = 13 and LN =√(89)

So that, HN = 13 - (13-3)/2 = 13 - 5 = 8

    LN =  \sqrt{(HN)^(2)+(LH)^(2)  }\n\n√(89) = \sqrt{(8)^(2)+(LH)^(2)  }\n\n89=64+(LH)^(2) \n\nLH=√(25)=5

Since,  HN  = 8. So that,  HK = 13 - 8 = 5

In a triangle, if two sides are equal. Then, opposite angle of both sides are also equal.

In triangle LKH,   LH = HK = 5 and \angle H=90

So that,     m∠LKN = 90/2 = 45 degree.

Hence, the angle  m∠LKN is equal to 45 degrees.

Answer:

The coordinates of mage of L(5, 10) will be: (11, 3)

So, the 4th (last) option is correct.

Step-by-step explanation:

As we know that Translation means how much a point is moved to the left/right and up/down.

  • Given the translation maps the point J(1, 4) onto K(7, -3).

As the x-coordinate of the image point K(7, -3) is 7 which is 6 units right to the original point J(1, 4).

Also, the y-coordinate of the image point K(7, -3) is -3 which is 7 units down to the original point J(1, 4)

so it means the translation basically implies that

(x, y) → (x + 6, y - 7)

Hence, the coordinate of the image of L(5, 10) can also be determined by

using the same rule.

(x, y) → (5 + 6, 10 - 7) = (11, 3)

Therefore,  the coordinates of mage of L(5, 10) will be: (11, 3)

So, the 4th (last) option is correct.

What is the absolute value of 0.6?

Answers

Answer:

0.6

Step-by-step explanation:

We are given that  0.6

We have to find the absolute value of 0.6

Absolute value of a number : it is defined as the magnitude of a number .

If a number x

Then, its absolute value is given by

\mid x\mid=x

It is always  positive because it is distance of a number  from zero .

Absolute value of 0.6 is given by

\mid 0.6\mid=0.6

the absolute value of 0.6 is 0.6 beacause its the same thing

What is the probability of rolling a number less than or equal to 8 with two dice, given that at least one of the dice must show a 6?

Answers

Answer:

(1)/(9)

Step-by-step explanation:

Events :

{1,1} ;{1,2};{1,3};{1,4};{1,5};{1,6}

{2,1} ;{2,2};{2,3};{2,4};{2,5};{2,6}

{3,1} ;{3,2};{3,3};{3,4};{3,5};{3,6}

{4,1} ;{4,2};{4,3};{4,4};{4,5};{4,6}

{5,1} ;{5,2};{5,3};{5,4};{5,5};{5,6}

{6,1} ;{6,2};{6,3};{6,4};{6,5};{6,6}

Total events = 36

Favorable events = Sum of number less than or equal to 8 with two dice, given that at least one of the dice must show a 6 = {1,6};{2,6};{6,1} ;{6,2} =4

Probability of getting an event = \frac{\text{Favorable events}}[\text{Total events}}

So,  probability of rolling a number less than or equal to 8 with two dice, given that at least one of the dice must show a 6 = (4)/(36)

                                                                       = (1)/(9)

Thus , the probability of rolling a number less than or equal to 8 with two dice, given that at least one of the dice must show a 6 is (1)/(9)

If one die shows 6, the second can be a maximum of 8-6=2. This leads to a probability of 2/6=1/3.
