Answer:

C. 254.34 in^2

Step-by-step explanation:

The formula for area of a circle is πr² (pi x radius x radius).

Here, only the diameter is shown.

To find the radius, divide the diameter by 2.

18 / 2 = 9

9 is the radius.

We use 3.14 as π (pi).

Now we have the final equation.

pi x radius x radius

3.14 x 9 x 9 = 254.34 in^2.

Therefore, the area of the circle is 254.34 in^2.

Answer:

have of 18 is 9

9^2 is 81

81 x 3.14(pi) = 254.34

Formula of area of a circle:

half of diameter or given radius squared

Times

3.14(pi) or whatever you use for pi.

Answer:

$f(x) = {sec}^{ - 1} x \\ let \: y = {sec}^{ - 1} x \rightarrow \: x = sec \: y\\ \frac{dx}{dx} = \frac{d(sec \: y)}{dx} \\ 1 = \frac{d(sec \: y)}{dx} \times \frac{dy}{dy} \\ 1 = \frac{d(sec \: y)}{dy} \times \frac{dy}{dx} \\1 = tan \: y.sec \: y. \frac{dy}{dx} \\ \frac{dy}{dx} = \frac{1}{tan \: y.sec \: y} \\ \frac{dy}{dx} = \frac{1}{ \sqrt{( {sec}^{2} \: y - 1}) .sec \: y} \\ \frac{dy}{dx} = \frac{1}{ |x | \sqrt{ {x }^{2} - 1} } \\ \therefore \frac{d( {sec}^{ - 1}x) }{dx} = \frac{1}{ |x | \sqrt{ {x }^{2} - 1} } \\ \frac{d( {sec}^{ - 1}5x) }{dx} = \frac{1}{ |5x | \sqrt{25 {x }^{2} - 1} }\\\\y=arccos(\frac{1}{x})\Rightarrow cosy=\frac{1}{x}\\x=secy\Rightarrow y=arcsecx\\\therefore \frac{d( {sec}^{ - 1}x) }{dx} = \frac{1}{ |x | \sqrt{ {x }^{2} - 1} }$

I will give Brainliest!!!

mixer [17]

Answer: C

Step-by-step explanation:

x = 2 $\sqrt{y+2}$ - 6

x + 6 = 2 $\sqrt{y+2}$

((x+6)/2 = $\sqrt{y+2}$ )^2

(x+6/2)^2 = y+2

y = (x+6/2)^2 -2

y= 1/4x^2 +3x +7
