Answer:

13. [tex]C=6\pi[/tex]

14. [tex]C=9\pi[/tex]

15. [tex]C=7\pi[/tex]

Step-by-step explanation:

To find the circumference of a circle, the formula is [tex]C=2\pi r[/tex], with "C" being the circumference and "r" being the radius.

In question 13, the radius (r) is shown as 3ft. When you put this into the equation, it should look like this:

[tex]C=2\pi (3)[/tex]

Simplify.

[tex]C=6\pi[/tex]

Follow the same steps in questions 14 and 15. In 14, 9 is the diameter, which makes the radius 4.5.

A shipping container has a volume of 48 cubic meters. What could be the dimensions (length, width, height) of the container if none of the dimensions are 1 m? Explain how you found the dimensions.

Answers

Answer:

6m * 4m * 2m

Step-by-step explanation:

Given that :

Cubic volume = 48 m³

Possible dimension if none of the dimensions is 1 m

Volumetric Dimension = (length * width * height)

The product of the three dimensions must give 48m³

Constraint : none of the dimensions has a volume of 1 m.

Hence, possible dimension :

6m * 4m * 2m = 48m²

Hence, one possible dimension is :

6m * 4m * 2m

Step-by-step explanation:

1 divided by 4 = 0.25

The value of the rational number rounded to the nearest hundredths is given by A = 0.25

What is rounding up numbers?

There are basically two rules while rounding up numbers

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

Non-zero digits are always significant

Zeros between non-zero digits are always significant

Leading zeros are never significant

Trailing zeros are only significant if the number contains a decimal point

Given data ,

Let the rational number be represented as A

Now , the value of A is

A = ( 1/4 )   be equation (1)

On simplifying , we get

The value of 1 divided by 4 is 25 %

So , A = 0.25

On rounding the number 0.25 to the nearest hundredths , we get

A = 0.25

Therefore , the value of A is 0.25

Hence , the rounded number is A = 0.25

to Solve Variation:

Direct Variation function is defined as the function where two quantities vary directly i.e. variables x and y are said to be directly varying if y = kx. Where;

k is the constant of variation.

Thus, from the options, we see that the function,

y = x varies directly with the constant of variation i.e. k = 1.

Similarly, y = ¹/₄x + 2 is also varying directly with constant k=1

find the value of x in a triangle. x-20, x+10, x-20

Answers

The value of the angles should be. (x-40°). , (x-20°), (½x-10°) , not (x-40°) + (x-20°)+(½x-10°)

Sum of all the interior angles of a triangle is 180°.

So a equation can be made by the given data,

(x-40°) + (x-20°) + (½ x-10°) = 180°

x-40°+x-20°+½x-10° = 180°

2x+½x -60°-10° = 180°

5/2 x - 70° = 180°

5/2 x = 180° + 70°

5/2 x = 250°

x = 250° × 2/5

x = 50° × 2

x = 100°

So the angles are

x-40° = 100°-40° = 60°

x-20° = 100°–20° = 80°

½x-10° = ½(100)° - 10° = 50° -10° = 40°

The answer can be checked by putting the values of the angle we got in the second statement i.e. Sum of all the interior angles of a triangle is 180°.

60° + 80° + 40° = 100° + 80° = 180°

Step-by-step explanation:

16x + 48

The greatest common factor of 16 and 48 = 16

Hence, expressing 16x + 48 in factored form:

16x + 48 = 16(x + 3)

28x + 32y

Greatest common factor of 28 and 32 = 4

Hence,

The area of the circle is equal to 144π square inches.

What is the area of the circle?

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.

Given that the circumference of a circle is 24π in. The area of the circle is calculated by the formula given below,

Area of circle = πr²

Circumference of the circle = 24π

2πr = 24π

r = 12

The area of the circle will be calculated as:-

Area = πr²

Area = π x ( 12 )²

Area = 144π square inches.

Hence, the area is 144π square inches.
