The volume of the cone is 1592.6 cm³

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.

The right circular cone's vertex is immediately above the base's centre. The line connecting the vertex with the centre point of the base is perpendicular to the cone's radius. A cone, on the other hand, can have its vertex anywhere.

Given that, a right circular cone with the height of 19.4 cm and a base with a diameter of 9.9 cm. we need to find the volume,

Volume of cone = 1/3 × π × radius² × height

= 1/3 × 3.14 × (9.9/2)² × 19.4

= 1592.6 cm³

Hence, the volume of the cone is 1592.6 cm³

Answer:

(5.5, 12.5) OR (11/2, 25/2)

I would put in the decimal value as the answer, but of you like then you can add the fraction as an answer.

Step-by-step explanation:

We are given the endpoints (-4, 15) and (22, 3) to find the midpoint. In order to find the midpoint, we will use its formula.

Midpoint formula :- (x1 + x2 / 2, y1 + y2 / 2)

(x1 + x2 / 2, y1 + y2 / 2)

(-4 + 15 / 2, 22 + 3 / 2)

(11 / 2, 25 / 2) ---> (5.5, 12.5) Midpoint

Answer:

(2, 6).

Step-by-step explanation:

The solution is the ordered pair where the 2 lines intersect.

Answer:

(2, 6)

Step-by-step explanation:

Take a look at the graph.

The problem has rather helpfully graphed out the two equations presented to us, and the point in which both lines intersect is (2, 6), making this pair your solution.

If you'd like to check, plug in the corresponding variables.

x = 2

y = 6

First equation:

y = x + 4

6 = 2 + 4

6 = 6

The equation is true.

Second equation:

y = -0.5x + 7

6 = (-0.5 x 2) + 7

6 = -1 + 7

6 = 6

This equation is true as well.

Answer:

4 hours

Step-by-step explanation:

As she wants to keep two candles burning so after3 hours only 2 candles will remain and after 4 hours only one but till 4 hours 2 candles would be burning that what she wanted so its 4 hours

If Dora burns candles that burn for 4 and 5 hours, they combine to burn for 9 hours.

Combination and permutation are two alternative strategies for organizing elements of a set into subsets in mathematics. The subset's components can be recorded in any order when combined. The components of the subset are stated in a separate order in a permutation.

Dora has three candles that will burn for 3, 4, and 5 hours, respectively.

The combination of the hours of burning,

3 + 4 = 7 hours

4 + 5 = 9 hours

3 + 5 = 8 hours

So the greatest number is 9

Thus, if Dora burns candles that burn for 4 and 5 hours, they combine to burn for 9 hours.

Answer:

2,10

Step-by-step explanation:

we can see where the line touches the x-axis but right at the line making the points have a 0 as the y, (2,0) and (10,0) the others have don´t have 0 in the y place. To make it short there are 2 points touching the x-axis, not above or below but on the line.  

Given:

Point = (1,-4), Slope - 8

Point = (1,5), Slope =1

To find:

The slope-intercept forms of the given lines.

Solution:

The slope intercept form of a line is:

[tex]y=mx+b[/tex]

The point slope form is:

[tex]y-y_1=m(x-x_1)[/tex]

where, m is the slope of the line.

We have, Point = (1,-4), Slope - 8. So, the equation of the line is:

[tex]y-(-4)=-8(x-1)[/tex]

[tex]y+4=-8x+8[/tex]

[tex]y=-8x+8-4[/tex]

[tex]y=-8x+4[/tex]

Therefore, the correct option is B.

We have, Point = (1,5), Slope =1. So, the equation of the line is:

[tex]y-5=1(x-1)[/tex]

[tex]y-5=x-1[/tex]

[tex]y=x-1+5[/tex]

[tex]y=x+4[/tex]

Therefore, the correct option is D.

Answer:

height for the building = 551.8 ft

Step-by-step explanation:

The info given describes the shape of a right triangle.

Thus:

Reference angle = Angle of elevation = 23°

Opposite side = height of the building = ?

Adjacent side = 1,300 ft

Apply trigonometric function, TOA:

Tan 23 = Opp/Adj

Tan 23 = Opp/1,300

1,300 × Tan 23 = Opp

551.817261 = Opp

Opp ≈ 551.8 ft

height for the building = 551.8 ft

Answer:

Step-by-step explanation:

I did the test and this is what it said in the review.

The new volume of the prism is 480 m³, option B is correct

A three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The total surface area of the prism is given by:

2lw + 2lh + 2wh = 360

Dividing both sides by 2, we get:

lw + lh + wh = 180

The volume of the prism is given by:

lwh = 60

Multiplying both sides by 8, we get:

8lwh = 480

Substituting 2l, 2w, and 2h for l, w, and h, respectively, we get:

(2l)(2w)(2h) = 8lwh

(2l)(2w)(2h) = 480

Simplifying, we get:

(2l)(2w)(2h) = 8lwh

8lwh = 480

Therefore, the new volume of the prism is 480 m³, option B is correct

6x+8 is ur answer

If  price of gas went up by 0.5% last month. Suppose gas currently costs $2.44 a gallon. If the price of gas continues to increase at this rate then 2.5864 cost on year from now

percentage, a relative value indicating hundredth parts of any quantity.

0.5% convert to decimal

0.5/100=0.005

We need to calculate what is 0.5 percentage of 2.44.

0.005×2.44=0.0122

The cost increases after one year i.e is twelve months.

0.0122×12=0.1464

Now add 0.1464 with 0.0122

2.44+0.1464

Two point five eight six four.

=2.5864

Hence 2.5864 is the price of gas after one year.

Answer:

$6725

Step-by-step explanation:

Given data

Princiapal= $5000

Rate=2.3%

Time= 15years

The function that will model this situation is given as

A=P(1+rt)

The above function is a simple interest function

Substitute our data we can find the amount A

A=5000(1+0.023*15)

A= 5000(1+0.345)

A=5000(1.345)

A=5000*1.345

A=$6725
