Answer:
Area of sector = 84.861
Step-by-step explanation:
Given
The radius of the circle = 9
central angle of sector = ![120^{o}](https://tex.z-dn.net/?f=120%5E%7Bo%7D)
value of pi π = 3.143
To find : the area of sector = ?
We know that the formula to calculate area of sector is given as:
area of sector = (π
Θ)/ ![360^{o}](https://tex.z-dn.net/?f=360%5E%7Bo%7D)
where, r is radius and Θ is the central angle of the sector
Substituting the known values in above formula, we get
area of sector = (3.143 x
x
) / ![360^{o}](https://tex.z-dn.net/?f=360%5E%7Bo%7D)
= 84.861
Hence area of sector is 84.861
