Therefore, <2 is going to be equal to the m< the corresponding angle in the other triangle. <2 = 61°

<2 is also equal to 61° by the interior angles theorem

Find the area of the shaded regions below. Give your answer as a completely

Eddi Din [679]

Answer:

$\huge\boxed{A_R=18\pi\ cm^2}$

Step-by-step explanation:

$\dfrac{80^o}{360^o}=\dfrac{8}{36}=\dfrac{2}{9}$

The shaded region is 2/9 of whole circle.

Calculate the area of a circle:

$A=\pi r^2$

$r$ - radius

Substitute $r=9cm$

$A_O=\pi\cdot9^2=81\pi(cm^2)$

Calculate the area of the shaded regions:

$A_R=\dfrac{2}{9}A_O\\\\A_R=\dfrac{2}{9}\cdot81\pi=2\cdot9\pi=18\pi(cm^2)$
