The radius of a circle is 3 inches . What is the circumference of the circle ?

Vlada [557]

Answer:

Option C

Step-by-step explanation:

Circumference of a circle is:

$C=2\pi r$

r - radius

We are given the radius of 3 inches.

$C=2\pi r\\\\C=2(3)\pi \\\\C=\boxed{6\pi }$

Option C should be the correct answer.

Hope this helps!

Complete the set of ordered pairs for the relation.

Nonamiya [84]

The set of ordered pairs are $(-2,18),(-1,20),(0,22),(1,24),(2,26)$

Step-by-step explanation:

Given that the relation $\{(x, y): y=2(x+11) \text { and } x \in(-2,-1,0,1,2)\}$

To find the set of ordered pairs, let us substitute the value for x in the relation $y=2(x+11)$

For $x=-2$ ,

$\begin{aligned}y &=2(-2+11) \\&=2(9) \\y &=18\end{aligned}$

The ordered pair is $(-2,18)$

For $x=-1$ ,

$\begin{aligned}y &=2(-1+11) \\&=2(10) \\y &=20\end{aligned}$

The ordered pair is $(-1,20)$

For $x=0$ ,

$\begin{aligned}y &=2(0+11) \\&=2(11) \\y &=22\end{aligned}$

The ordered pair is $(0,22)$

For $x=1$ ,

$\begin{aligned}y &=2(1+11) \\&=2(12) \\y &=24\end{aligned}$

The ordered pair is $(1,24)$

For $x=2$ ,

$\begin{aligned}y &=2(2+11) \\&=2(13) \\y &=26\end{aligned}$

The ordered pair is $(2,26)$

Thus, the set of ordered pairs is $(-2,18),(-1,20),(0,22),(1,24),(2,26)$

Que signifuca (1,r) en matematicas?

velikii [3]

Hello from MrBillDoesMath!

Answer:

(1,r) is point on the Cartesian plane

Discussion:

(1,r) is an ordered pair with a first component (the "x" component) and a second component (the "y" component). In this case (1,r) appears to be a point (punto) whose x coordinate is 1 and whose y coordinate is "r"

Thank you,

MrB
