How do you find the length of a circle in geometry?

Answers

Answer 1

Answer: Exactly the same way you find any missing item in any other subject:
You take the information you're given, and you collect everything you know about
relationships between the information you have and the item you have to find.
Finally, you use the relationships and the given information to find the value of the
missing item.

The process you'll use to find the circumference of a circle will depend on what
information you DO have about the circle.

Answer 2

Answer: the length of the circle is the same thing as its circumference
circumference= 2×π×radius²

Answers

Using a 1-sample z-interval for the population proportion with confidence level 0.997, the sample probability is 0.69 with margin of error of 0.16, so between 0.69+0.16=0.85 of the population and 0.69-0.16=0.53 of the population prefers coffee. 84% and 54% are the correct answers.

Death Valley CA is 282 feet below sea level. Black Mountain, KY is 750 feet above sea level . How many more feet above sea level is Black Mountain than Death Valley?

Answers

From the Death Valley to Black Mountain, it rises 1032 feet because Death Valley is 1032 ft lower than Black Mountain in elevation.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

It is given that:

Death Valley CA is 282 feet below sea level.

Black Mountain, KY is 750 feet above sea level.

Death Valley (282ft) + 282ft = sea level (0).

0 + 750ft = Black Mountain (750ft).

282ft + 750ft = 1032ft.

From Death Valley to Black Mountain, it rises 1032 feet. Death Valley is 1032 ft lower than Black Mountain in elevation.

Thus, from the Death Valley to Black Mountain, it rises 1032 feet because Death Valley is 1032 ft lower than Black Mountain in elevation.

Death Valley (282ft) + 282ft = sea level (0).

0 + 750ft = Black Mountain (750ft).

282ft + 750ft = 1032ft.

It takes 1032ft to get from Death Valley to Black Mountain. Black Mountain is 1032ft more feet above sea level than Death Valley. Hope that helps! :)

What is the sum of 3/4 and 18/19 closest to 0 1 or

Answers

to solve this, you must find a common denominator (the number on the bottom of the fraction) before adding the numbers. The easiest was to do this is multiply the denominators together to get a common product. You then multiply by that number over itself, because that is equivalent to 1. So in this problem, you would multiply 3/4 by 19/19 and 18/19 by 4/4. Once you do this, you can add the fractions together.

A city is adding a brick border around the community garden. The garden has the dimensions of x ft by x ft. The dimension of the brick border are x + 12 ft by x + 12 ft. What is the area of the brick border

Answers

Answer:

The area of the brick border is $(24x+144)\ ft^(2)$

Step-by-step explanation:

we know that

The area of the brick border is equal to

$A=(x+12)(x+12)-(x)(x)\n \nA=(x+12)^(2) -x^(2)\n \nA=x^(2)+24x+144-x^(2)\n \nA=(24x+144)\ ft^(2)$

A school club is raising money for a trip, and needs to reach $10,000. Their fundraising progress is modeled by the function f(x) = 435 + 1200x, where x is measured in weeks. What is the meaning of the coefficient 1200?

Answers

f ( x ) = 435 + 1200 x
They had $435 to start with ( b = 435 ) and 1200 is the slope ( m ) in the formula:
y = m x + b
The coefficient 1200 means the money they get per one week ( $1,200 ).
We can also solve the equation:
10,000 = 435 + 1,200 x
1,200 x = 9,565
x = 9,565 : 1,200 = 7.97 ≈ 8 weeks
