Finding Circumference

Answers

Answer 1

Answer:

Step-by-step explanation:

Determine the radius of a circle. ...

Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 14 = 87.9646 cm .

You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm² .

Answer:

h + c = 3 and 4h + 4c =10

No solutions

Step-by-step explanation:

If hot dogs = h, and chips = c,

Then the first scenerio can be written as h + c = 3

The second scenerio is 4h + 4c = 10.

So, your system should be

h + c = 3 and 4h + 4c =10

Solve this system

First, solve c + h = 3 for c.

Subtract h on both sides.

c = -h + 3

Then, substitute c = -h + 3 into the second equation (4c + 4h = 10)

4(-h + 3) + 4h = 10

Simplify.

- 4h + 12 + 4h = 10

12 = 10

This is not right, so this system has no solutions. This means that there is no set cost for the chips or hot dogs (or for both).

Answer:

i think a triangle

Step-by-step explanation:

whats the formula for the surface area of a triangle?

Answers

Answer:

use the formula A = 1/2bh, where A = area, b = base, and h = height. Once you have the areas of all sides and faces, you simply add them together to get the surface area.

Hope this helps!

The formula would be depending on the triangular shape. Triangular prisms have their own formula for finding surface area because they have two triangular faces opposite each other. Which creates the formula A=12bh is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height.

What year(s) did the cities have the same population? What was the population of both cities during the year(s) of equal population? Answers: (year 1995, 425000 people) and (year 2022, 1910000 people)

Answer: hope this helps love.

Step-by-step explanation:

years of equal population are 1995 and 2022.

in 1995, population was 425,000 people and in 2022, population was 1,910,000 people.

Step-by-step explanation: Baskinville: y = x2 - 22x + 350

Cryersport: y = 55x - 950

Note that x2 is xsquare not x2

Resolving the quadratic equations carefully will give the values of y and x which represent the population and years.

2 1/4 ⋅ 1 2/3
as a mixed number

Answers

Answer:

[tex]3\frac{3}{4}[/tex]

Step-by-step explanation:

We have two mixed numbers and are asked to multiply them together.

2 1/4 * 1 2/3

First we convert the mixed numbers into improper fractions to make it easier for us. So follow the MA rule.

Multiply the whole number by the denominator and add the numerator.

2 1/4 * 1 2/3

9/4 * 5/3

Now multiply across,

[tex]\frac{9*5}{4*3}[/tex]

[tex]\frac{45}{12}[/tex]

Now we need to convert this back into a mixed number.

So how many times does 45 go into 12?

3 times, and 3 are left.

[tex]3\frac{3}{4}[/tex]

Simplify given fraction into mixed fraction is 3³/₄
