The area of sector is 1.57 m²
<u>Explanation:</u>
Given:
Radius, r = 3 m
Central angle of a sector = 1/9π radians
Area of sector, A = ?
We know:
Area of sector, A = ![\frac{1}{2} r^2 \alpha](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20r%5E2%20%5Calpha)
where,
α is the central angle in radians
On substituting the value we get:
![A = \frac{1}{2} X(3)^2 X \frac{1}{9}X 3.14\\ \\A = 1.57 m^2](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20X%283%29%5E2%20X%20%5Cfrac%7B1%7D%7B9%7DX%203.14%5C%5C%20%5C%5CA%20%3D%201.57%20m%5E2)
Therefore, the area of sector is 1.57 m²
