The area of a circle is r^2 x PI

r is half the diameter = 21mm

Area = 21^2 x PI

area = 441pi

Answer:

$13x - 4 = 8x + 11 \\ 13x - 8x = 4 + 11 \\ 5x = 15 \\ \frac{5x}{5} = \frac{15}{5} \\ x = 3$

NOW LET'S FIND THE VALUE OF AD

$ad \: \: length = 13x - 4 \\ \\ x = 3 \\ \\ 13x - 4 \\ 13 \times 3 - 4 \\ 39 - 4 \\ = 35$

Which of the sets of ordered pairs represents a function.

Lana71 [14]

So what makes a function a function is that each input (x) only has one output (y).

Set A is not a function because when x = 2, y = -2 and 3.

Set B is not a function because when x = 9, y = 3 and -3.

In short, the correct option is "Neither A nor B".

Masteriza [31]

They played 82 games.....they won 44.....so they lost (82 - 44) = 38

ratio of wins to loses...
they won 44
they lost 38
the ratio would be : 44/38 which reduces to 22/19 or 22:19 or 22 to 19

How do you factor m^2=2m?<br><img src="https://tex.z-dn.net/?f=m%20%5E%7B2%7D%20%20%3D%202m" id="TexFormula1" title="m ^{2} = 2

Sonbull [250]

First move all terms to one side:

$m^2=2m\implies m^2-2m=0$

Then all terms on the left side share a common factor of $m$ :

$m(m-2)=0$

The zero product product property says that if $ab=0$ , then $a=0$ or $b=0$ . So either $m=0$ or $m-2=0\implies m=2$ .
