What is the volume of the cone in the diagram

Answer:

103.18units³

Step-by-step explanation:

Area of the sector DEF = theta/360 * πr²

r is the radius

theta is the angle subtended at the centre

theta =70 degrees

radius DE = 13units

Substitute

Area of the sector = 70/360 * 3.14(13)²

Area of the sector = 7/36 * 530.66

Area of the sector = 3,714.62/36

Area of the sector = 103.18units³ (to the nearest hundredth)

Answer:

Change in price = 0.154

Step-by-step explanation:

Given that,

The price on Monday = 24.85

The price on Friday = 25.004

We need to find the change in price from Monday to Friday. It can be calculated as follows :

Change = 25.004 - 24.85

= 0.154

So, the required change in the price is equal to 0.154 .

11x+6=12x-4

Answer: 2/3

Step-by-step explanation:

In the number cube, the possible numbers that can be gotten when it is rolled are 1, 2, 3, 4, 5 and 6.

We should note that when 2 or 4 is not rolled, there'll be 4 other numbers which can be rolled and they're 1, 3, 5 and 6.

Therefore, the probability of not rolling a 2 or 4 on a number cube having sides labeled with numbers 1-6 will be 4/6. This can be further reduced to 2/3

Look, I’m sorry but I couldn’t find the number of days so your choices are ether A or D. 800 x 3.125 = 2500. I multiply 3.125 and 1.5 but got 4.6875

Answer:

5.3!

Step-by-step explanation:

( in case you need work ) the angles are congruent so you set them equal to each other!

6x+12=9x-4

you then get 16=3x then divided its 5.3!

Answer: RM 5200

Step-by-step explanation:

Principal = RM5000

Rate = 4%

Time = 1 year

Simple Interest = PRT

= 5000 × 4% × 1

= 5000 × 0.04 × 1

= 200

Now, the total savings will be the addition of the principal and the interest which will be:

= RM 5000 + RM 200

= RM 5200

Given:

The phrase is "six times a number is less than negative thirty-nine and three-quarters".

To find:

The inequality represented by the given phrase.

Solution:

Let x be the unknown number.

Six times a number is "6x".

Less than is "<".

Negative thirty-nine and three-quarters is "[tex]-39\dfrac{3}{4}[/tex]".

So, six times a number is less than negative thirty-nine and three-quarters is:

[tex]6x<-39\dfrac{3}{4}[/tex]

Therefore, the correct option is C.

Answer:

"six times a number is less than negative thirty-nine and three-quarters".

Answer:

$203.04

Step-by-step explanation:

The computation is shown below:

23 ounces to be $0.36

And,

69 ounces be  x

So here x

= (69 ounces × $0.36) ÷ 23 ounces

= $1.08

Since there is 188 samples, so the total value is  

= $1.08 × 188

= $203.04

=========================================

The diagram shows:

Recall that the area of a parallelogram is equal to the base times height

area = base*height

We're told that the area is 117 square units, so that means 13x = 117.

Divide both sides by 13 to isolate x

13x = 117

13x/13 = 117/13

x = 9

The height of the parallelogram is 9

Note how:

area = base*height = 13*x = 13*9 = 117

which helps confirm we have the correct height value for x.

Answer:

The volume of the Rubik's Cube is 27 in^3

Step-by-step explanation:

Each face of a Rubik's Cube has 3x3 cubes, then each face has 9 small cubes.

We can think of a Rubik's Cube as 3 pieces, such that each piece has 9 small cubes on it, and the 3 pieces are: Front side, middle part, back part.

Then the total number of small cubes on a Rubik's cube is 9*3 = 27 small cubes.

Now we know that each one of these small cubes has a volume of 1 in^3

Then the volume of 27 of these cubes is 27 times the volume of a single smaller cube, then the volume of the Rubik's Cube is:

V = 27*( 1 in^3) = 27 in^3

Answer:

d = 4cm

Step-by-step explanation:

curved surface area (CSA) of cylinder = [tex]2\pi rh[/tex]

h = 28cm and CSA = 352[tex]cm^{2}[/tex]

[tex]2\pi rh[/tex] = 352

2 * [tex]\frac{22}{7}[/tex] * r * 28 = 352

[tex]r = \frac{352*7}{2*22*28}[/tex]

after calculating, you will get r = 2cm

so diameter = 4cm

3,456 m²

Step-by-step explanation:

i just took the test :)

The surface area of the given Square pyramid is 3456 square meters.

The area or region that an object’s surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has. There are numerous shapes and dimensions in geometry, including spheres, cubes, cuboids, cones, cylinders, etc. Each form has its own volume and surface area.

Given, a square pyramid with a base side of 36m and a slant height of 30m.

From the general formula of the surface area of the square pyramid,

Surface area = area of base + 4* area of triangle

Surface area = 36*36 + 4 * 1/2*36 * 30

Surface area = 3456 m²

therefore, the surface area of the given Square pyramid is 3456 square meters.

Answer:

Step-by-step explanation:

Here f(x) = x^2 - 2x - 5, which at x - -5 is 25 +10 - 5 = 30 and at x = 6 is 19.

The average value of a function f(x) over an interval [a, b] is

                  f(b) - f(a)

ave. val. = ---------------

                     b - a

which in this particular case is

                     19 - 30

ave. val. = ----------------- = -11/11 = 1

                     6 - (-5)

The average value of this function f(x) = x^2 - 2x - 5 on [-5, 6] is 1.

Answer:

The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.
