Find the value of x.

Answer:

4 squared is 16 so 16 times 3.14= 50.24

Step-by-step explanation:

Answer:

4^2 = 16

16 x 3.14 = 50.24 in2

Step-by-step explanation:

Formula of area of a circle:

π x r^2(radius being squared)

To make it more easier:

3.14 or 22/7 x radius^2

Some keywords:

Radius: Half of your diameter or given radius

Radius Squared: Your radius squared, your radius to the power of 2.

Pi: 3.14 or 22/7 depending on what they tell you to use for pi

Given:

In ΔJKL, m∠L=90°, JL = 80, KJ = 89, and LK = 39.

To find:

The value of sine of ∠J.

Solution:

In a right angle triangle,

[tex]\sin\theta =\dfrac{Perpendicular}{Hypotenuse}[/tex]

In triangle JKL,

[tex]\sin J =\dfrac{LK}{KJ}[/tex]

[tex]\sin J =\dfrac{39}{89}[/tex]

[tex]\sin J =0.4382[/tex]

[tex]\sin J \approx 0.44[/tex]

Therefore, the value of sine of ∠J is about 0.44.

Answer:

60°

Step-by-step explanation:

Given :

DAB= (180 – 3x) °,

mZ B= (6x – 40) °, and

m ZC = (x+20) °.

DAB = mZ B + m ZC ( the exterior angle equal the sum of the two opposite interior angles)

180 - 3x = (6x - 40) + (x + 20)

180 - 3x = 6x - 40 + x + 20

180 - 3x = 6x + x - 40 + 20

180 - 3x = 7x - 20

180 + 20 = 7x + 3x

200 = 10x

x = 200/10

x = 20

Angle B = 6x - 40 = 6(20) - 40 = 120 - 40 = 80

Angle C = x + 20 = 20 + 20 = 40

BAC = 180 - (80 + 40) (SUM OF ANGLES IN A TRIANGLE)

BAC = 180 - 120

BAC = 60°

Answer:

9x² + 6xy + y²

Step-by-step explanation:

(a + b)² =  a² + 2ab + b²

a  = 3x

b = y

(3x +y)² = (3x)² + 2*3x*y + y²

            = 9x² + 6xy + y²

(3x)² = 3²*x² = 3*3*x² = 9x²

Step-by-step explanation:

Cone

The volume of a cone is linked to the volume of a cylinder. A cone is one third of the volume of a cylinder. The volume of a cone is ¹/₃ × π × r² × l. To calculate the volume we multiply these values together. The answer will be written in units³.

Sphere

The volume of a sphere is ⁴/₃ × π × r³. To calculate the volume we multiply these values together. The answer will be written in units³.

Cylinder

The volume of a cylinder is π × r² × l (r is the radius of the circle and l is the length of the cylinder). To calculate the volume we multiply these values together. The answer will be written in units³. It is more accurate to use π = 3.142 or the π button on a calculator.

   A cone is a 3D shape with 2 faces and one edge

   A sphere is a 3D shape. It has one continuous face and no edges

   A cylinder is a type of prism. It has 3 faces and 2 edges

Answer:

Overall, it depends what type of coin you are using because each ones size is different. Or, if you are referring to the riddle it will be just one coin.

The correct answer is approximately 3,968 coins can be placed in the empty money box based on estimation. Based on these calculations, you can roughly estimate  a volume  calculation that  place around 7936 coins in your empty money box, assuming the coins are similar in size to a quarter.

To estimate the number of coins that can fit in your money box, we need to consider the volume of the box and the volume of a single coin.

Calculate the volume of the money box:

Volume = Length * Width * Height

Volume = 10 inches * 10 inches * 5 inches

Volume = 500 cubic inches

Estimate the volume of a single coin. Let's assume a common coin, such as a quarter:

Diameter of a quarter ≈ 0.96 inches

Thickness of a quarter ≈ 0.07 inches

Volume of a coin ≈ π * ([tex]radius^2[/tex]) * thickness

Volume of a quarter ≈[tex]3.14 * (0.48) ^2 * 0.07[/tex]inches

Volume of a quarter ≈ 0.063 cubic inches

Calculate the number of coins that can fit in the money box:

Number of coins ≈ Volume of the money box / Volume of a coin

Number of coins ≈ 500 cubic inches / 0.063 cubic inches

Number of coins ≈ 7936 coins (approximately)

Therefore, approximately 3,968 coins can be placed in the empty money box based on estimation. Based on these calculations, you can roughly estimate  a volume  calculation that  place around 7936 coins in your empty money box, assuming the coins are similar in size to a quarter.

find the volume of a sphere. Only a single measurement needs to be known in order to compute the volume of a sphere and that is its diameter. For example, if the diameter is known to be 20 feet, then calculate the volume by using the first formula above to get 4/3 x 3.14159 x (20/2) 3 = 4.1866 x 1000 = 4188.79 ft 3 (cubic feet).

Answer:

1.2km is 400% of 300m

Step-by-step explanation:

1 km=1000m

So,1.2 km=1000*1.2=1200m

Let 1.2km(or 1200m) be x% of 300 m

By the problem,

300*x/100 = 1200

Or, 3x=1200

Or,x=1200/3=400

1.2km is 400% of 300m

Step-by-step explanation:

A table is a 3-D object. It makes no sense to talk about reflecting it across a point or line. If the table is reflected across a vertical plane, the top will remain "up" and the legs will remain "down".

A glide reflection across a vertical plane will result in a functioning table.

Answer:

x = 10

Step-by-step explanation:

Angles in a triangle add up to 180°. Using this, we can form the following equation:

71° + 50° + 6x - 1 = 180. A simplified version is this: 120° + 6x = 180

Remove 120° from both sides to get:

6x = 60

Divide both sides to get:

x = 10

Answer:

Your answer is B

Step-by-step explanation:

The lowest number is 4, therefore it cannot be C.

Now you'll have to cross out numbers on both sides and your mean will be 9 because you'll have to add 8 and 10 together and 18 divided by 2 is 9.

Next, put a line between 8 and 10, now the 8 side is the lower quartile and the 10 side is the greater quartile.

For the lower quartile, add 7 and 7 together, divide 14 by 2 and the lower quartile is 7.

For the greater quartile, add 11 and 13 together, that's 24, divide 24 by 2 and that's 12.

Lowest: 4

Mean: 9

Lower quartile: 7

Greater quartile: 12

Highest: 14

Therefore your answer is B and not A or C.
