A circle with the diameter of 20 mm is showing what is the exact Sir conference obvious and then question to what is the approxi

yaroslaw [1]

Answer:

The approximate circumference is 62.8 mm

Step-by-step explanation:

Circumference is basically the perimeter of the circle

Circumference is given by

$2 *\pi *r$

Here the diameter is 20 mm, so the radius will be half of diameter = 10 mm

Substituting the given values, in above equation, we get -

Circumference =

$2 *3.14 * 10 \\62.8$ mm

The approximate circumference is 62.8 mm

PLEASE I NEED HELP WITH THIS I WILL MARK AS BRILLIANT PLS!!

Answer:

Number 7: $m=\frac{6}{4}$

This graph displays the change in wage per years of service. Since the slope is positive, this means the wage has a positive growth.

Number 8: $m=\frac{-400}{3}$

This graph displays the amount of people evacuating per hour. Since the slope is negative, this means the amount of people evacuating per hour is reducing.

Step-by-step explanation:

Number 7:

Step 1: Identify the points on the line to use for slope formula.

The two points are (2, 11) and (6, 17).

$x^1$ and $y^1$ will be $(2,11)$

$x^2$ and $y^2$ will be $(6, 17)$

Step 2: Plug in points into slope formula.

$m=\frac{y^2-y^1}{x^2-x^1}$

$m=\frac{17-11}{6-2}$

Step 3: Subtract.

$m=\frac{6}{4}$

Step 4: Simplify.

improper fraction: $\frac{3}{2}$

mixed number: $1\frac{1}{2}$

decimal: $1.5$

Number 8:

Step 1: Identify the points on the line to use for the slope formula.

The two points are (3, 1200) and (6, 800)

$x^1$ and $y^1$ will be $(3,1200)$

$x^2$ and $y^2$ will be $(6, 800)$

Step 2: Plug in points into slope formula.

$m=\frac{y^2-y^1}{x^2-x^1}$

$m=\frac{800-1200}{6-3}$

Step 3: Subtract.

$m=\frac{-400}{3}$

Step 4: Simplify.

Cannot be simplified further.

mixed number: $m=\frac{-400}{3}$

decimal: $133.333333333$
