How do you find the circumference of a circle? Please include an example if you’d like.

Answers

Answer 1

Answer:

Step-by-step explanation:

Plug the given value of the diameter into the formula and solve.[2]

Example problem: You have a circle tub with a diameter of 8 feet, and you want to build a white fence that creates a 6-foot wide space around the tub. To find the circumference of the fence that has to be created, you should first find the diameter of the tub and the fence which will be 8 feet + 6 feet + 6 feet, which will account for the entire diameter of the tub and fence. The diameter is 8 + 6 + 6, or 20 feet. Now plug it into the formula, plug π into your calculator for its numerical value, and solve for the circumference:

C = πd

C = π x 20

C = 62.8 feet

Answer:

Julie is Incorrect

Step-by-step explanation:

Given the data:

1 3/4, 2 1/2, 2, 2 3/4, 1, 1 3/4, 1 1/4, 3, 3 1/4, 3 3/4, 2, 2

The least amount of time spent is : 1

The most amount of time spent is : 3 3/4

From Julie's assertion, that the most amount of time spent is equal to 1 1/2 the least amount of time spent.

Most amount of time = 1 1/2 * least amount of time

3 3/4 = 1 * 1 1/2

15/4 = 3/2

However, 15/4 ≠ 3/2

Hence, Julie is incorrect

Given: Regular pyramid DO = 6, m ADO : 42°, AO Perpendicular (FBCD) Find: V and Surface Area Of ABCDF

Answers

Answer:

Assumed the base is a square

Find the height:

h / DO = tan 42°h = 6 tan 42° ≈ 5.4 units

Find the side of base:

a = 2DO/√2 = √2DO = 6√2 ≈ 8.5 units

Find volume:

V = a²h/3 = 8.5²(5.4)/3 ≈ 130.1 units³

Find the surface area:

S = a² + 4*1/2*a[tex]\sqrt{(a/2)^2+h^2}[/tex] = 8.5² +  2*8.5 [tex]\sqrt{(8.5/2)^2+5.4^2}[/tex] ≈ 189.7 units²

Answer:

the height of pyramid

tan 42°=h/ DO

h=6 tan 42° = 5.4 units

the side of base a = 2DO/√2 = √2DO = 6√2 = 8.5 units

volume= V = a?h/3 = 8.52(5.4)/3 = 130.1 units

surface area{S }= a + 4×1/2×a/(a/2)² + h² =

8.5²+ 2*8.5 √((8.5/2)² + 5.4²)= 189.7 unit²

Value of y

✰ [tex] \underline{ \underline{ \large{ \tt{S \: O \: L \: U \: T \: I \: O\: N}}}} : [/tex]

Basically there are two ways to find out the value of y. I'm gonna show you the both ways.

First one :

Find out the value of x first :

[tex] \large{ \tt{x + 25 \degree + 35 \degree = 180 \degree}} \text{(Sum \: of \: angles \: of \: a \: triangle)}[/tex]

⇾ [tex] \large{ \tt{x + 60 \degree = 180 \degree}}[/tex]

⇾ [tex] \large{ \tt{x = 180 \degree - 60 \degree}}[/tex]

⇾ [tex] \large{ \tt{x = 120 \degree}}[/tex]

Now ,Find out the value of y

[tex] \large{ \tt{x + y = 180 \degree}} \text{(Sum \: of \: angle \: in \: a \: straight \: line})[/tex]

⤑ [tex] \large{ \tt{120 \degree + y = 180 \degree}}[/tex]

⤑ [tex] \large{ \tt{y = 180 \degree - 120 \degree}}[/tex]

⤑ [tex] \boxed{ \large{ \tt{y = 60 \degree}}}[/tex]

Another way :

[tex] \large{ \tt{y = 35 \degree + 25 \degree}} [/tex] ( Exterior angle is equal to the sum of two non - adjacent interior angles )

↦ [tex] \boxed{ \large{ \tt{y = 60 \degree}}}[/tex]

➝ [tex] \large{ \boxed{ \boxed{ \tt{Our \: Final \: Answer : \underline{y = 60 \degree}}}}}[/tex]

what dose x repsent​

Answers

1. 4 (x+2)=28

Simplifying

4(x + 2) = 28

Reorder the terms:

4(2 + x) = 28

(2 * 4 + x * 4) = 28

(8 + 4x) = 28

Solving

8 + 4x = 28

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-8' to each side of the equation.

8 + -8 + 4x = 28 + -8

Combine like terms: 8 + -8 = 0

0 + 4x = 28 + -8

4x = 28 + -8

Combine like terms: 28 + -8 = 20

4x = 20

Divide each side by '4'.

x = 5

Simplifying

x = 5

2. 2 (x+4)=28

Simplifying

2(x + 4) = 28

Reorder the terms:

2(4 + x) = 28

(4 * 2 + x * 2) = 28

(8 + 2x) = 28

Solving

8 + 2x = 28

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-8' to each side of the equation.

8 + -8 + 2x = 28 + -8

Combine like terms: 8 + -8 = 0

0 + 2x = 28 + -8

2x = 28 + -8

Combine like terms: 28 + -8 = 20

2x = 20

Divide each side by '2'.

x = 10

Simplifying

x = 10

Answer:

  x = 5

Step-by-step explanation:

Perhaps you want to solve for x the rational equation ...

  (2+5x)/(3x) = (7x -18 +2x)/(3x)

Multiplying by 3x and collecting terms, we have ...

  2 +5x = 9x -18

  20 = 4x . . . . . . add 18-5x to both sides

  5 = x . . . . . . . . divide both sides by 4

The solution is x=5.

With a special church service and an elaborate party, this celebration is like having a wedding for a 15th birthday party. But it has been and still can be a simple thing, such as a dinner with family members after church. The Quinceaera [keen-say-ahn-YAY-rah] marks a girl's arrival, at age 15, into adulthood. At this point, she is expected to take more responsibility, to give more to her family and society. This is celebrated in many Hispanic communities in the United States as well as in Mexico, Central America and the Caribbean.Both the party and the service may involve a lot of decorations and music. In the church service, the fifteen-year-old reaffirms her baptismal and confirmation vows. With her is a "court of honor." Traditionally, this is a group of 14 pairs of boys and girls, a little younger than she is, and her escort. Often, though, the size and age of this group vary. The boys are called "chambelanes" [chahm-bay-LAH-nays] or lords, and the girls are "damas" [DAH-mahs], or ladies. The girl's "court" enters the church first, and then she walks down the aisle with her parents.Later the same day, a party takes place. This is most likely in a community hall or the family's house or yard. A special waltz by the girl with her father begins the dancing. Food and a specially decorated cake of many layers are served.The birthday girl often receives several symbolic gifts this day. They may include a doll her last child's toy a ring or other jewelry, her first high-heeled shoes and a bouquet of flowers. She wears a crown of flowers and a dress much like a wedding dress.This celebration is strongest in Mexico, where it may have its origins. The idea seems to come from an Aztec, or ancient Mexican, custom. In that culture, at age 12 or 13, a girl began to attend one of two types of school, depending on her future. Either she trained for religious service or for married life. The Spanish Catholic society adopted this idea, but changed the age to 15. Also, over time, instead of marking a choice of religion or marriage, the day became a rite of passage for all girls.2Select the correct answer.Here is a question from the text aids: What is the party usually like?A. It's just a typical birthday party.B. It has decorations, dancing and a big cake.C. The passage only describes the church service.
