Answer:

Step-by-step explanation:

Alright lets get started.

Please refer the diagram attached.

we have given the angle of the sector is $\frac{5\pi }{4}$ and radius is 8ft

Now, the area of sector = $\frac{1}{2}*angle*radius^2$

area= $\frac{1}{2} *\frac{5\pi }{4}*8^2$

area= $40\pi$

Answer $40\pi$

Sector area = central angle (degrees / 360) * PI * radius^2
Sector area = (225 / 360) * PI * 64
Sector area = .625 * 201.0619298297 
Sector area = 125.66

Which is the first step in simplifying the expression?

Elenna [48]

$\dfrac{3}{2 + \sqrt{2} }$

To rationalise the denominator, this is a standard step:
$= \dfrac{3}{2 + \sqrt{2} } \times \dfrac{2 - \sqrt{2}}{2 - \sqrt{2}}$

Answer: Option A

---------------------------------------------------------------------------------------------------

Let me continue to complete the question, though it is not ask for

$= \dfrac{3(2 - \sqrt{2})}{(2 + \sqrt{2)}(2 - \sqrt{2}) }$

$= \dfrac{3(2 - \sqrt{2})}{4 - 2 }$

$= \dfrac{6 - 2\sqrt{2}}{2 }$
