Answer:

perimeter of a circle=2πR

The perimeter of a circle is the circumference of the circle.

CIRCUMFERENCE

There are two formulas:

1. C = πd (use if the problem gives you the diameter only)

2. C = 2πr (use if the problem gives you the radius only)

AREA

There are several area formulas for a circle but I think for you at your level of math, A = πr^2 is all you need to know.

Kurt says factors and multiples are
maxonik [38]

<u>Step-by-step Explanation:</u>

<em>Before heading towards the solution, you need to make sure how multiple and factors are related to each other.</em>

<em>The multiple of a number could be obtained by multiply it with another number. </em>

For example, the first five multiples of 12 are 12, 24, 36, 48 and 60

  • 1 X 12 = 12
  • 2 X 12 = 24
  • 3 X 12 = 36
  • 4 X 12 = 48
  • 5 X 12 = 60

<em>Factors are the numbers that are multiplied to get a given number.</em>

For example,

  • 1 X 12 = 12
  • 2 X 12 = 24
  • 3 X 12 = 36

The factors of 12 are 1, 2, 3, 4, 6 and 12.

As division and multiplication can be used to find factors and multiples.

For example a whole number is a multiple of its factors.

Let w = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20} be the set of even wholes numbers from 2 to 20.

As 2 is a factor of 20 because 20 ÷ 2 = 4

20 is a multiple of 2 because 2 X 10 = 20

So, in the same way, the equation 8 X 5 = 40 can be used to determine how factors and multiples are related.

Let the equation be

                                    8 X 5 = 40

8 is a factor of 40 because 8 X 5 = 40

40 is a multiple of 8 because 40 ÷ 5 = 8

<em>So, this is how factors and multiples are related to each other.</em>

What is the slope of the line with equation 6x+3y=12?
max2010maxim [7]

Answer:

<h2>The slope m = -2</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

<em />

We have the equation in the standard form:

6x+3y=12

Convert to the slope intercept form:

6x+3y=12              <em>subtract 6x from both sides</em>

3y=-6x+12           <em>divide both sides by 3</em>

y=-2x+4

slope: <em>m = -2</em>

y-intercept: <em>b = 4</em>

A school choir needs to make T-shirts for its 75 members and has set aside some money in their budget to pay for them. The membe
Rzqust [24]

Answer:

The equation that represents the relationship between the number of T-shirts ordered, the number of colors on the shirts, and the total cost of the order  is Y = $225 +  X × $50

Where;

Y = The total cost of the order

X = The number of colors on the shirts

Step-by-step explanation:

The number of T-shirts required by the members of the school choir = 75

The amount charged by the printing company per shirt = $3

The charge for each color to be printed on the shirts = $50

The number of T-shirts ordered = 75

The charge per shirt = $3

The number of colors on the shirts = X

The fee per color on the shirts = $50

The total cost of the order = Y

Therefore, we have;

The basic cost of printing the 75 shirts = The charge per shirt × The number of T-shirts ordered

∴ The basic cost of printing the 75 shirts = $3 × 75 = $225

The total fee of the added colors to the shirt = The number of colors on the shirts × The fee per color on the shirts

∴ The total fee of the added colors to the shirt = X × $50

The total cost of the order, Y = The basic cost of printing the 75 shirts + The total fee of the added colors to the shirt

∴ Y = $225 +  X × $50

The equation is therefore;

Y = $225 +  X × $50.

Find the area of the circle.<br> Use 3.14 for π.<br> d = 10 cm<br> A = [?] cm²<br> A=TCr2
Stells [14]

Answer:

78.5

Step-by-step explanation:

The diameter (d) is equal to the radius x 2, so take half of d to get r. Use r (5) in the equation to get your answer.

A= 3.12 x 5^2

A= 78.5
