Answer:

≈ 565.5 units²

Step-by-step explanation:

The area (A) of the shaded sector = area of circle × fraction of circle

A = πr² × \frac{162}{360} ← r is the radius

   = π × 20² × \frac{162}{360}

   = 400π × 0.45 ≈ 565.5 units²

Answer:

<h2>f(19) =  -  \frac{27}{7}  \\</h2>

Step-by-step explanation:

f(x) =  \frac{3}{x + 2}  -  \sqrt{x - 3}  \\

To find f(19) , substitute the value of x that's 19 into f(x). That is for every x in f (x) replace it with 19

We have

f(19) =  \frac{3}{19 + 2}  -  \sqrt{19  - 3}  \\  =  \frac{3}{21}  -  \sqrt{16}  \\  =   \frac{1}{7}  - 4 =  \frac{1 - 28}{7}

We have the final answer as

f(19) =  -  \frac{27}{7}  \\

Hope this helps you
