Find the Circumference of a circle with a Diameter of 9 inches Group of answer choices 9 pi inches 9 pi inches^2 9 pi inches^3 1

katen-ka-za [31]

Answer: $9\pi\ in.$

Step-by-step explanation:

Given

The diameter of a circle is $d=9\ in.$

So, the radius is $r=\frac{d}{2}=4.5\ in.$

The circumference is given by $2\pi r$

Insert the values

$\Rightarrow 2\pi \cdot 4.5\\\Rightarrow 9\pi \ in.$

Thus, the circumference of the circle is $9\pi\ in.$

Is (1, 3) a solution to the system of inequalities below?

Oxana [17]

<h3>Substitute and Check:</h3>

$y > 2x + 1 \\ 3 > 2(1) + 1 \\ 3 > 3 \\ false$

<h3>We can stop here and conclude that ( 1 , 3 ) is not a solution to this system, since it does not even satisfy the first equation, but check for the other one just in case:</h3>

$y < - 3x \\ 3 < - 3(1) \\3 < - 3 \\ also \: false$
