Step-by-step explanation:

The formula is given by :

$s=\dfrac{m}{360}\times 2\pi r$

We have,

m = 19° and d = 9 cm

So,

$s=\dfrac{19}{360}\times 2\pi \times \dfrac{9}{2}\\\\s=1.49$

Hence, this is the required soltion.

What is the area of the shaded region? O 21 mm² O24 mm² O 42 mm² 48 mm²

Ivanshal [37]

24 mm^2

Reasoning:
The area of the big triangle will be: (6+4+2)(5)(0.5). The answer will be equal to 30 mm^2. The area of the smaller triangle will be: (4)(3)(0.5). The answer will be 6 mm^2. Next, subtract the area of the larger triangle by the smaller triangle (30-6). The final answer will then be 24mm^2.

Sorry if this may have been confusing. I had to do this on my phone.
