What is the approximate circumference of the circle shown below?

iVinArrow [24]

If we know the value of r (radius) we can find the circumference of circle using formula $Circumference=2\pi r$

Step-by-step explanation:

We need to find the circumference of circle.

Since the picture is missing in the given question so I will explain the method to find the circumference of circle.

You can use this method to find circumference of the given question.

The formula used to find circumference of the circle is

$Circumference=2\pi r$

Where π is pie and its value is 3.14

and r is radius of circle

So, if we know the value of r (radius) we can find the circumference of circle using formula $Circumference=2\pi r$

Rewrite each expression as a polynomial in standard form: x^2-5x+6 ÷ x-3 + x^3-1 ÷ x-1

iragen [17]

Answer:

So in standard form equation will be $x^2+2x-1$

Step-by-step explanation:

We have given expression $\frac{x^2-5x+6}{x-3}+\frac{x^3-1}{x-1}$

Let first we solve first part of the expression

So $\frac{x^2-5x+6}{x-3}=\frac{x^2-3x-2x+6}{x-3}=\frac{(x-3)(x-2)}{x-3}=x-2$

Now second part $\frac{x^3-1}{x-1}$

We know the algebraic identity $a^3-b^3=(a-b)(a^2+ab+b^2)$

So by using this identity

$\frac{x^3-1}{x-1}=\frac{(x-1)(x^2+x+1)}{x-1}=x^2+x+1$

Now adding first and second part

$x-2+x^2+x+1=x^2+2x-1$

So in standard form equation will be $x^2+2x-1$
