Question

Plz help with this problem, I will give brainliest to whoever answers this question.

Answer 1

Radius of circle = 9 yd

Angle AOB = 120° = α

Area Of Circle =

$\pi{r}^{2}$

$81\pi \: {yd}^{2}$

Area of sector AOB =

$\frac{ \alpha }{360} \: \pi{r}^{2}$

$\frac{120}{360} \times \: 81\pi$

$27\pi \: yd {}^{2}$

Area Of Sector ADB =

$81\pi \: - \: 27\pi$

$54\pi \: {yd}^{2}$
